6ba9f702ba [bazel] Try adding cc_binary rules that use generated rules
To make the atomic rules a bit easier to work with, in many
of the folders, this adds in cc_library rules to group
together the sources from that folder (and subfolders
where prudent). We only needs sources because those atoms
should have their headers as deps.

One issue that was pointed out is that there is currently
no way to restrict the inclusion of certain packages,
a la, `gn check`. For example, there is no mechanism from
stopping a dev from adding
#include "modules/canvaskit/WasmCommon.h"
to something in //src/core (except circular dependencies).
We can probably address that using Bazel's visibility
rules as needed:
https://docs.bazel.build/versions/main/visibility.html
https://docs.bazel.build/versions/main/be/functions.html#package_group

It is recommended to look at this CL patchset by patchset.
PS1: Update gazelle command to generate rules in more folders.
PS2: A few changes to make generation work better.
PS3: The result of running make generate in //bazel
PS4: Adding the rules to build sksllex, the simplest binary I
     could find in the Skia repo.
PS5: Adding the rules to build skdiff, a more complex binary.
     I tried a few approaches, but ended up gravitating back
     towards the layout where we have each folder/package
     group up the sources. I imagine at some point, we'll have
     skdiff depend on skia_core or something, which will
     have things like //src/core, //src/codecs, //src/pathops
     all bundled together.
PS7: Added in the groupings of sources, similar to what we had
     earlier. I liked these for readability. These helped fix
     up the //:skia_core build, and by extension, the CanvasKit
     build.

b500ef7a76 Add some precision back to timestamps when using --trace
Optimizations to JSON size (%f -> %g) changed the meaning of the digits
argument, causing these timestamps to become severely truncated. Traces
have been fairly useless as a result (too many events starting/stopping
at the same time). This adds enough digits back that things are better.

   - removed -Idirectives from BUILD.gn
   - various compile.sh simplifications
   - tweak tools/embed_resources.py
   - update gn/find_headers.py to write paths from the top
   - update gn/gn_to_bp.py SkUserConfig.h layout
     so that #include "include/config/SkUserConfig.h" always
     gets the header we want.

84836b799a moar static flags
Like any normal variable, flags can be made file-scoped static,
and like any normal variable, mostly they should be if they can.

This CL converts most flags to be static, if only so that the
ones that do cross files stand out more clearly, and so that
there's more examples of static flags through the codebase for
people to ape.

b6f8212bff Optimize the size of our JSON
Catapult (Chrome tracing) has a hard upper limit of 256 MB of JSON data.
This is independent of the number of events, because V8 can't store a
single string longer than that. Before these changes, longer traces
(eg all GL GMs, which was my test case) would be much larger (306 MB).

This CL includes four changes that help to reduce the text size:

1) Offset timestamps (saved 7.3 MB)
2) Limit timestamps and durations to 3 digits (saved 10.7 MB)
3) Shorten thread IDs (saved 7.2 MB)
4) Omit categories from JSON (saved 25.7 MB)

Note that category filtering still works, this just prevents us from
writing the categories to the JSON, which was of limited value.

At this point, my 306 MB file is now 255.3 MB, and loads.

69fd008199 Added SkJSONWriter
This is a stand-alone helper class for writing properly
structured JSON to an SkWStream. It currently solves two
problems (although this CL only uses it in one context):

1) Performance. Writing out JSON this way is about 10x
faster than using JSONCPP. For the large amounts of data
generated by the tracing system, that's a big win.

2) Makes it easy to emit structured JSON from code that's
not fully centralized. We'd like to spit out JSON that
describes a GrContext, GrGpu, GrCaps, etc... Doing that
with simple string manipulation is complex, and spreads
this logic over all those functions. Using JSONCPP adds
yet another (large) third party library dependency (that
we only build into our own tools right now).

This went through several revisions. I originally planned
it as a stateful SkString wrapper, so the user could just
build their JSON as a string. That's O(N^2), though,
because SkString grows by a (small) constant amount. Even
using a better growth strategy still means needing RAM
for all the resulting text, which is usually pointless.
This version has a constant memory cost, so writing huge
amounts of JSON to disk (tracing a long DM run can emit
100's of MBs) doesn't stress resources.

3bf0042caa ok, basic tracing support
This doesn't do anything in the default process-per-task mode, because
those child tasks exit using _exit(), which doesn't trigger the event
tracer destructor to flush.

I don't remember exactly why I exit with _exit(), so I'm going to have
to follow up on that.  But written this way as I think I'm at least
initializing the tracing in the right place for each process for the
future.

In threaded (-j -1) and serial (-j 0) modes, everything seems to work
great.

I'm also thinking I might add a tracer like the SkDebugf tracer but
using ok_log(), which handles interlaced logging from concurrent tasks
better than vanilla SkDebugf.

Example:
    ninja -C out ok; and out/ok gm 8888 filter:search=fontmgr_bounds trace -j -1

de6e5bf33f Tracing cleanup and bugfixes
TraceID was unused, remove it.

Simplify casting logic by using the same union helper as the macros.
This fixes a bug that was present in the bool handling - we were
treating the union value as a pointer, so we were dereferencing
random stack memory. Luckily it never crashes, we did get the wrong
values for bools.

53136aa93f First stab at JSON event tracer
Not yet thread safe (so it forces threading off).
Builds JSON on the fly, so overhead is certainly bad.
Plan to fix all of that, but this at least "works".

There is now one tracing flag: 'trace'.
- 'debugf' installs the SkDebugf tracer.
- 'atrace' installs the Android ATrace tracer.
- Any other value is interpreted as a filename, and
  produces a JSON file for chrome://tracing.

All three modes work in DM, nanobench, and Viewer.
