Docserver: Introduce an annotation to CompiledFileSystem's compilation function

which indicates it only relies on that data from a single file, not multiple
files. This allows implementing an optimisation where the file data doesn't need
to be re-compiled if the file stat is the same (note that it's never re-read because
CachingFileSystem already implements a similar optimisation).

This also replace a couple of uses of CompiledFileSystem.Create with the
appropriate CompileFileSystem.For* method.
