Revert "Enable gn check for all build targets."

This reverts commit 61bc38fd52.

Reason for revert: Appears to have broken the Dawn->Chromium autoroller, which is now seeing Abseil linking issues on Mac and Linux.

Example failing roll: https://chromium-review.googlesource.com/c/chromium/src/+/3590451/

Example error log: https://logs.chromium.org/logs/chromium/buildbucket/cr-buildbucket/8816532799903001889/+/u/compile__with_patch_/stdout

Original change's description:
> Enable gn check for all build targets.
>
> This CL removes the `check_targets` entry from the .gn file which
> will enable checking all targets. Two of the GN targets have had
> missing dependencies added.
>
> The `gn/abseil-cpp/BUILD.gn` was referenced against the Chromium
> BUILD.gn for abseil to make sure the `public_deps` and `deps`
> match in the two versions. The paths are re-written to match
> the Dawn paths.
