Support mechanism to select a specific version of module sdk prebuilt

This CL is scoped to cc_* module types. With trunk stable, we will have
multiple prebuilts of the cc modules in
prebuilts/module_sdk/art/<v>/host-exports/, and this CL introduces a
mechanism to use apex_contributions to select a specific versioned
prebuilt when building.

If a soong module is selected using apex_contributions, all rdeps will
get that soong module, which includes
- rdep soong modules which might be depending on it via Android.bp
- Soong's rule builder HostToolPath API

Implementation details: Create a new source_module_name property to
identify the root module. rdeps referring to the root module will get
redirected if necessary. This property also
becomes the stem, if `stem` is not set explicitly.

Bug: 322175508

Test: Added a unit test
