Original change's description:
> [rust] Component builds support: `std`, `serde_core`, `read_fonts`.
>
> This CL changes the `--crate-type` of `std`, `serde_core`, and
> `read_fonts` crates from `rlib` to `dylib` when `is_component_build`.
> In the future we may want to automatically opt-in all `cargo_crate`
> `rlib`s into `override_crate_type_as_dylib_in_component_builds`, but for
> now this is postponed into a follow-up bug: https://crbug.com/505430456
>
> The primary goal of this CL is to change the crate type of the `std`
> crate (to fix https://crbug.com/498216362), but covering `serde_core`
> and `read_fonts` crates is required to avoid ODR violations related to
> trait implementations for `std` (and `core`) types - e.g.:
>
> ```
