Revert "Reland "[webui] Create //ui webui_code_cache_resources bundle""

This reverts commit 9499f74458641207d1a4574024e789394d40131e.

Reason for revert: Causing official Mac builds to fail.

Original change's description:
> Reland "[webui] Create //ui webui_code_cache_resources bundle"
>
> This is a reland of commit fcf9034d123bc4314d8191a6c1dea0e872f1e95a
>
> See diff against PS1.
>
> MSan builds use hermetic instrumented system libraries, and so
> instrumented binaries only run when the system libraries match the
> version of the prebuilt msan-instrumented libraries. For that reason,
> it's recommended to run msan-built binaries under docker.
>
> However, for host binaries that's not easily doable. This reland
> specifically disables code_cache_generator for msan builds when the
> host and target toolchains are the same.
>
> Note: When they're not the same it's all good and the host toolchain
> doesn't instrument. See crbug.com/40055221#comment17 for context.
