gpu-dawn: fix git error when fetching Dawn source

Browse source 
Previously, when the gpu-dawn SDK attempted to fetch Dawn sources, Git
failed with this error:

```
fatal: ambiguous argument 'generated-*': unknown revision or path not
in the working tree.
Use '--' to separate paths from revisions, like this:
'git <command> [<revision>...] -- [<file>...]'
```

This caused the whole build to fail as the gpu-dawn SDK is unable to
check out the intended revision of the generated Dawn sources. This
commit fixes the issue by using `git checkout --force` instead of
`git reset --hard`, which works because you can checkout to a detached
commit hash (used by DirectXShaderCompiler, for example) as well as an
actual branch.

The alternative would be to do `git reset --hard origin/generated-*`
rather than `git reset --hard generated-*`, but that would require
modifying Wrench unlike this solution.
