We need to specify attribute locations and (sometimes) frag shader
output locations. Desktop GL worked fine without this, but Flutter
ran into this problem, and a Pixel 2 reproduced the issue.
Note that both APIs (BindFragDataLocation and BindAttribLocation)
don't take effect until the next time the program is linked, so
we have to relink the program after applying those changes.
I was afraid that re-linking would eliminate the perf benefits of
pre-compiling the shaders, but (at least on Pixel 2) that's not
the case. I traced the life of a single program, and the initial
link (during precompile) was 4.4 ms. The re-link took 0.23 ms.

The client can do a test run of their application with
a persistent cache set to SkSL mode. They store the key
and data blobs that are produced.
Ship those blobs with the application. At startup, call
GrContext::precompileShader for each key/data pair. This
compiles the shaders, and stores the GL program ID, plus
a small amount of metadata in our runtime program cache.
Caveats:
* Currently only implemented for the GL backend. Other
backends will require more metadata to do any useful
amount of work. Metal may need a more drastic workflow
change, involving offline compilation of the shaders.
* Currently only implemented for cached SkSL (not GLSL
or program binaries). Supporting other formats again
requires more metadata, and the cached shaders become
increasingly specialized to GPU and driver versions.
* Reusing the cached SkSL on different hardware is not
supported. Many driver workarounds are implemented in
the SkSL -> GLSL transformation, but some are higher
level. Limiting device variance by artificially hiding
extensions may help, but there are no guarantees.
* The 'gltestprecompile' DM config exercises this code
similarly to 'gltestpersistentcache', ensuring that
results are visually identical when precompiling, and
that no cache misses occur after precompiling.

The majority of our gm testing has been disabling nvpr, which doesn't
match our real-world behavior where we use nvpr whenever available.
This CL fixes the issue by completely removing the explicit nvpr
configs. Now if we have nvpr, you get it.
This CL also lowers the nvpr priority in the path renderer chain and
adds a "NonNVPR" job on Quadro where we can continue to test our
non-nvpr codepaths on NVIDIA.

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.
