Fix inclusive language presubmit

The current presubmit has the filter inverted so it would only attempt
to match the filtered files. The file name also has to be converted to
`LocalPath` otherwise it's attempting to compare a python object to a
string and always fails to match.

 Dawn relies on a lot of code generation to produce boilerplate code, especially webgpu.h-related code. They start by reading some JSON files (and sometimes XML too), process the data into an in-memory representation that's then used by some [Jinja2](https://jinja.palletsprojects.com/) templates to generate the code. This is similar to the model/view separation in Web development.

 Using a seed corpus significantly improves the efficiency of fuzzing. Dawn's fuzzers use interesting testcases discovered in previous fuzzing runs to seed future runs. Fuzzing can be further improved by using Dawn tests as a example of API usage which allows the fuzzer to quickly discover and use new API entrypoints and usage patterns.
 
 Dawn has a CI builder [cron-linux-clang-rel-x64](https://ci.chromium.org/p/dawn/builders/ci/cron-linux-clang-rel-x64) which runs on a periodic schedule. This bot runs the `dawn_end2end_tests` and `dawn_unittests` using the wire and writes out traces of the commands. This can manually be done by running: `<test_binary> --use-wire --wire-trace-dir=tmp_dir`. The output directory will contain one trace for each test, where the traces are prepended with `0xFFFFFFFFFFFFFFFF`. The header is the callsite index at which the error injector should inject an error. If the fuzzer doesn't support error injection it will skip the header. [cron-linux-clang-rel-x64] then hashes the output files to produce unique names and uploads them to the fuzzer corpus directories.
