[debugger] Add DWARF typed stack entry

Add support for typed stack entries in the DWARF expression evaluator.
This allows DWARF expressions to explicitly do signed, unsigned, or
floating-point math.

This does not actually implement the new DW_OP_*_type or the casts that
can actually generate typed stack entries. That will be done in a
followup (it requires more plumbing that will be easier to implement and
review separately).

Instead, the new typed entries are tested by explicitly pushing stack
entries and then running operators over them.
