Prebuilts that were not overriding a source module would never
get UsePrebuilt set, which would cause SkipInstall() to be called,
and prevent the module from being exported to make.

Directly using blueprint.BaseDependencyTag might cause issues because
if other modules also use blueprint.BaseDependencyTag, the
different type of modules will be mixed when fetched based on Tag.

In lieu of having an environment variable to override prebuilts
preferences (for now), fall back to prebuilts whenever the source
module is disabled. Complicated source modules (like LLVM) that
already have Go logic can then use an environment variariable to
disable their source module whenever they want to use prebuilts.
Computes UsePrebuilt once using information from both the source
and prebuilt modules, and stores the result in the prebuilt module.

If the source module is being used instead of the prebuilt module,
disable installing the prebuilt module.

Support prebuilt shared libraries as an initial proof-of-concept of
prebuilts. Future changes will support binaries and static libraries,
and the ability to select which to use based on something besides
blueprint properties.
