Reland "[fuzzer] Remove GL from (now-Vulkan) build"

This is a reland of 805acda3f3aa3d9fc85c84bac5aa52c472ec3bb1

It fixes the #if SK_GL which was causing the Android roll
to fail.

This disables unit tests on Test-Ubuntu18-Clang-Golo-GPU-QuadroP400-x86_64-Release-All-TSAN_Vulkan
which were consistently crashing with OOM.

Original change's description:
> [fuzzer] Remove GL from (now-Vulkan) build
>
> The fuzzer runs against the Vulkan version of Swiftshader.
> There are no libGL.so (etc) on the fuzz runtime, so we
> want to avoid linking against those.
>
> The GL code that is #ifdef'd out is still necessary to
> avoid timeouts on TSAN with our NVIDIA jobs.

> Procedure for testing this locally (and iterating):
>   1. In oss-fuzz checkout, run
>      `python infra/helper.py shell skia`
>      to pull up local interactive version of Docker
>      fuzzer build image.
>   2. Run `compile` in fuzzer shell. Stop after
>      the swiftshader compiles and is copied into /out
>      with Ctrl + C.
>   3. Comment out the swiftshader compilation part [1]
>      (no need to re-do this when modifying Skia code).
>      `apt-get install nano -y`
>      `nano ../build.sh`
>   4. Make change to Skia repo using normal methods.
>   5. Run the following in the Skia repo
>      `git diff origin main > foo.patch`
>      Copy the patch into the Docker shell using Ctrl+C
>      and nano.
>   6. Apply the patch inside the Docker shell
>      `git apply foo.patch`
>      and re-compile (which should skip right to
>      building the fuzzer libs)
>      `compile`
>   7. Repeat 4-7 or make small changes directly in
>      the Docker shell via nano.
>   8. When compilation and link succeeds, run
>      `ldd /out/api_mock_gpu_canvas`
>      to verify GL and friends were not dynamically linked.
