Allow setting tags on files

This does not affect FuseSoC, but allows Edalize backends to take different decisions depending on which tags that are set. Use-cases for this is to mark HDL source files as simulation files to avoid having them being sent to synthesis, and marking which tool in a flow that should consume a particular TCL file.
