Simplify it by using a common array for the fibonacci number.
Add unit tests to check extreme limits.

There's no reason to use std::aligned_storage when it's simpler to use
an array and alignas(). This way you don't have to remember whether the
template arguments are size-then-align or align-then-size, you don't
have to remember to use the _t variant or typename ... ::type, and
there's no risk to forgetting the alignment parameter entirely.
It doesn't look like this was deprecated, but I still think this paper
makes good arguments for why we shouldn't use it:

SkArenaAlloc has three fields that are used only for reset. Make a
subclass called SkArenaAllocWithReset which has the three
fields, and has the reset functionality.
An example of a reset() that is used instead of using a better scope
is PathOpsAngleAfter in PathOpsAngleTest.cpp.

This fixes a large number of SkSL namespaces which were labeled as if
they were anonymous, and also a handful of other mislabeled namespaces.
Missing namespace-end comments have been added throughout.
A number of diffs are just indentation-related (adjusting 1- or 3-
space indents to 2-space).

This partially undoes 774168efac "Allow
CCPR in DDL mode (take 2)". The issue appears to have been the use of a
not fully defined type (destructor could not be instantiated) because
the private fields were also dllexported, requiring the destructors to
exist in all translation units which included the header. Only the parts
of the class which are actually public are now marked as exported.

Current strategy: everything from the top
Things to look at first are the manual changes:
- added tools/rewrite_includes.py
- 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.

I'm looking at making SkArenaAlloc independent of Skia.
Here's a bit of low-hanging fruit.
Nothing is using makeSkSp(). Good... it seems real dangerous.
