This is needed now that we force the user to explicitly choose between
disabling use of SPIRV-Tools, using a version installed on the system,
or using the version obtained by update_glslang_source.py
The VS2015 bazel test has been stopped, so we can not remove the config
file. We have the windows-msvc-2019-release-bazel to replace it. It is
already running, and it is passing.
The `windows-msvc-2015-release-bazel` build config name is misleading.
It now runs VS2019. We should rename it. This is the first part: create
the new config files.
In the docker build script that Kokoro runs, the directories
are owned by a different user. Git complains about that and in the GN
flow GN will error out.
In this docker flow we don't care about that warning, so within
the docker config set a git global option to ignore the issue.
Add missing `.cfg` files for GN presubmit.
Add missing `recursedeps` in the `DEPS` file.
Call `./update_glslang_sources.py` before attempting to build.
Add more GN spew to the `.gitignore` file.
Allows for testing of generation of both static libraries and shared objects.
The old configs are staying in place until I'm confident everything is working correctly.
