Add support for custom bindgen binaries.
In some cases customized logic is required to generate the expected
bindgen bindings. This adds support for rust_bindgen modules to define a
HostTool module to use instead of bindgen.
Bug: 161816141
Test: New Soong tests pass.
Test: Local test case shows custom_binary module being used for bindgen
generation.
