ANGLE has implemented extension to support for texture_rectangle. Check
for its existence as well as GL_ARB_texture_rectangle extension.
Intended to follow up on Chrome side to avoid copy into texture 2d for
PaintCanvasVideoRenderer.

With the more agressive abandonment of the GrContext state in https://skia-review.googlesource.com/c/skia/+/137121 (Fix abandonment of programs) (i.e., nulling out of the interface) it is necessary to add more guards so that we don't try calling GL methods when the context has been abandoned.

Most of this is (obviously) not necessary to do, but once
I started, I figured I'd just get it all. Tools (nanobench,
DM, skiaserve), all GMs, benches, and unit tests, plus support
code (command line parsing and config stuff).
This is almost entirely mechanical.

This reverts commit 00f8866a32.
Reason for revert: Seems to be breaking angle test bots. Eg:

Many tests and examples use drawText with
a guess of how long the text is in bytes,
or a call to strlen(). Add a helper to
SkCanvas to simplify these examples.
Add another helper for SkString.

'static const' means, there must be at most one of these, and initialize it at
compile time if possible or runtime if necessary. This leads to unexpected
code execution, and TSAN* will complain about races on the guard variables.
Generally 'constexpr' or 'const' are better choices. Neither can cause races:
they're either intialized at compile time (constexpr) or intialized each time
independently (const).
This CL prefers constexpr where possible, and uses const where not. It even
prefers constexpr over const where they don't make a difference... I want to have
lots of examples of constexpr for people to see and mimic.
The scoped-to-class static has nothing to do with any of this, and is not changed.
* Not yet on the bots, which use an older TSAN.

Uses textureSize() to unnormalize texture coords when reading from a RECTANGLE texture. Because of this we also require a later GLSL version to use rectangle textures (1.40).
Note that this causes a issue with the bicubic effect. The texture coords seem to have poor precision and the result is ugly. textureSize() is intended as a workaround until effects can be updated to handle unnormalized coords themselves.
Updates places where we were looking for OpenGL version 3.2 for rectangle support. It was actually added in 3.1.
