gdb: Remove stabs support from dbx

This commit makes it so reading dbx inferiors will not read stabs
debuginfo from the inferiors.

This has the side effect of making reading DBX inferiors a noop.  It
will be removed in a future commit, however, the present series of
commit is focused on just removing stabs.
