[XLA] Remove the "hlo dumper" parameter of xla::Compiler and its piping.

This dumper is no longer necessary since the restructuring of HLO dumping and
the addition of MaybeDumpHloModule which heeds to the right flags. The
remaining bits didn't have additional functionality, but constituted a lot of
boilerplate that has to be propagated throughout the backends.
