[SwiftCompilerModules] Link lib_InternalSwiftSyntaxParser to libswift

To use _RegexParser from SwiftSyntax.

* Create 'libswiftCompilerModules_SwiftSyntax.a' which is a subset of
  'libswiftCompilerModules.a'
* Link 'lib_InternalSwiftSyntaxParser' to
  'libswiftCompilerModules_SwiftSyntax.a'
* Factor out swift runtime linking logic in CMake so that dynamic
  libraries can link to Swift runtime, in addition to executables
* Link 'lib_InternalSwiftSyntaxParser' to swift runtime
