Blink is migrating away from SkBitmaps, so we need an SkImage-based
SkImageFilter source. This is pretty much a 1-1 equivalent of
SkBitmapSource.
To avoid duplication, relocate the SkImage deserialization logic
from SkPictureData to SkReadBuffer.

Possible follow-up changes to consider
1. Roll SkImage_Raster and _Gpu into _Generator, where the generator (or cacherator) is backed by a pre-existing texture or raster.
2. Evolve SkImageUsageType into a verb requiring stretching, and have the caller (common code) digest the caps() and usage, so that subclasses are just told what to do (stretch or not)
3. Common code/utility to convert an unstretched texture into a stretch one (and cache it) if the generator can only make an unstretched one.

To match Chrome, make sure we've disabled thread-safe statics, RTTI, and exceptions. Linux needed -fno-threadsafe-statics, Mac needed all three.
Nothing important triggered this CL. I just got confused when I saw exception handling (calls to delete, stack unwinding) in some generated code on my laptop.

The newly created VisualLightweightBenchModule is just the old VisualBench.cpp, but gutted to only include timing code.
Future CLs will harden this abstraction, but for this CL the module owns a backpointer to VisualBench.cpp for a couple of calls.

The million SKPs generated require >5T of storage. A good deal
of that are copies of system fonts.
Chrome built with
#DEFINE SK_WHITELIST_SERIALIZED_TYPEFACES
will omit the font data if the font matches a precomputed
checksum.
The captured SKP prepends sk_ to the names of fonts that
have their data omitted. The SKP consumer can either add
renamed fonts from the recording machine, or add
gDeserializeTypefaceDelegate = WhitelistDeserializeTypeface;
which strips the sk_ prefix when deserializing typefaces.
whitelist_typefaces --check
Computes the checksums of fallback
fonts and returns 0 if the checksums match the checked-in
file SkWhitelistChecksum.cpp.
whitelist_typefaces --generate
Writes an updated version of SkWhitelistChecksum.cpp.

The motivation for this was to remove SK_OFFSETOF from SkTypes, but
this CL is mostly about cleaning up our use of offsetof generally.
SK_OFFSETOF is removed to SkTypes and added to the two places it is
actually used (for the non standard behavior of finding the offset of
fields in types which are not standard layout).
Older versions of gcc required POD for offsetof to be used without
warning. Newer versions require the more relaxed standard layout.
Now that we no longer build on older versions of gcc, remove the
old warning suppressions.
PODMatrix is renamed to AggregateMatrix. SkMatrix is already POD
(trivial and standard layout). The PODMatrix name implies that the
POD-ness is needed for the offsetof, but it is actually the aggregate
attribute which is needed for compile time constant initialization.
This makes it more obvious that this can be revisited after we can
rely on constexpr constructors.
This also adds skstd::declval since this allows removal of existing
awkward code which casts a constant to a pointer to find the size of
a field.

No API change, only removes unused macro.

This is a follow-up to https://codereview.chromium.org/1290423007/,
with a couple small changes:
- turn on AVX and AVX2 for Windows using /arch ('EnabledEnhancedInstructionSet')
- reformat and de-conditionalize where possible / irrelevant
Picked up this while poking around in libvpx's Chrome GYPs.
And yes, AVX = 3, AVX2 = 5. Don't even ask what 4 means...

CL (1 of 3) adds empty lists in our .gypi,
and builds the files in those empty lists with the appropriate flags.
CL (2 of 3) will have Chrome's GYP and GN files read these lists,
and build them with the appropriate flags.
CL (3 of 3) will add runtime detection and stub files to the lists
with empty Init_sse42(), Init_avx(), Init_avx2() methods.
After that, we should be able to use SSE 4.2, AVX, and AVX2 if desired.
Some motivation:
- SSE 4.2 adds some sweet string-oriented methods that
can help us write fast high quality 32-bit hashes.
- AVX is SSE doubled, e.g. 8 floats or two SkPMFloat at a time.
- AVX2 is SSE2 doubled, e.g. 8 pixels at a time.

SkTemplates.h contains a number of Skia specific utilities which are
not designed for external use. In addition to reducing the external
support burden, this will allow Skia to freely refactor this file.

This also:
makes the SkLightingShader handle normal maps where the rects aren't aligned between the diffuse and normal maps.
adds a light aggregating class (Lights) to SkLightingShader (along with a Builder nested class).
