[bazel] Integrate rom_ext_image_tools into `sw/host` cargo workspace

To facilitate mask ROM E2E testing, test binaries must be signed in
order to be runnable via the mask ROM. To add signing support to bazel
for test images, the `rom_ext_signer` tool must be brought under bazel
control.

To enable the above, this commit integrates the `rom_ext_image_tools`
into the `sw/host` cargo workspace, and re-runs `cargo raze` to generate
the appropriate bazel BUILD files for the `rom_ext_image_tools` Rust
dependencies.

This addresses a task in #10864.
