Add libraryDependencyTag to track dependencies on static and shared libraries

dependencyTag uses a set of predefined tags to identify different types
of dependencies.  There are already multiple bits of metadata stored
in the dependency tag (Library, Shared, ReexportFlags), and supporting
them all requires a combinatorial explosion of predefined tags and
causes issues when using equality comparisons if a new bit of metadata
is added.

Add a new libraryDependencyTag type that will contain the metadata
bits, and replace the quality comparisons with checks on the metadata
bits.

There are 5 TODOs where modifying the checks identified problems with
the existing checks.  These were left in place to produce identical
build output and will be fixed separately.
