Delete some dumping flags.
Delete some dumping flags.

Removed

  --jax_dump_hlo_graph
  --jax_dump_hlo_unoptimized
  --jax_dump_hlo_optimized
  --jax_dump_hlo_per_pass
  --jax_hlo_profile

All of these flags have an equivalent in XLA which you can pass via
XLA_FLAGS.  I'm trying to change the XLA_FLAGS, so I either need to
upgrade these to match or remove them.  Since they're not adding any
functionality you can't access via XLA_FLAGS, removing them seems
cleaner.
