Support mechanism to select a specific version of module sdk prebuilt

This CL is the platform_compat_config equivalent of aosp/2928483.

{prebuilt_}_platform_compat_config are collated by
`global_compat_config` via a singleton. The collated data is then used
in some CTS tests. At ToT, we ensure that the collation ignores the
platform_compat_config of prebuilt when source is selected, and vice
versa.

With trunk stable, multiple versions of prebuilt apexes and prebuilt
platform compat configs might exist in the tree. This CL uses
`Source_module_name` to hide the platform compat configs of the
unselected prebuilt apexes.
