Claudio DeSouza f9824de76f [cr137][rust] Use serde_json vendored by upstream 
As this crate is now a dupicate, this change removes the version under
brave and checks out the one by upstream.

    [ChromeML] Import of llguidance Rust crate

    This CL is to import the llguidance Rust crate. llguidance is going to
    be used by the Prompt API to reduce the compatibility risk of having
    browsers returning results of different format due to different ML
    models or different versions of the same ML model.

    Most of the changes are automatically generated by tools mentioned in:
    https://chromium.googlesource.com/chromium/src/+/HEAD/docs/rust.md#importing-a-crate-from-crates_io

    When adding llguidance, the lark feature is added to avoid lark reference build errors. ./tools/crates/run_gnrt.py add llguidance --
    --no-default-features -F lark

    Some changes edited manually:
    - remove group = 'test' entries for '[crate.anyhow]'
      from third_party\rust\chromium_crates_io\gnrt_config.toml. This is to avoid
    'testonly = true' entries in generated BUILD.gn files since llguidance
    is not for testonly

    - replace CRLF by LF in third_party/rust/chromium_crates_io/vendor/derivre-v0_3/SUPPORT.md

    - infra\inclusive_language_presubmit_exempt_dirs.txt is updated to add
      exception for third_party\rust\chromium_crates_io\vendor\serde_json-v1\.github\workflows\ci.yml:58
