Deprecate MHLO input conversion pipeline (#13870)

As we continue the migration to the stablehlo input conversion pipeline,
mark the mhlo pipeline as deprecated and rename the option to
`--iree-input-type=mhlo_legacy`.

This was proposed and announced in the following RFC:
https://groups.google.com/g/iree-discuss/c/s6dBpDtWhtk.

Users are encouraged to try the new pipeline:
`--iree-input-type=stablehlo` and report any issues or missing features,
as we plan to drop the legacy mhlo pipeline in a few weeks.

Update tests to use the new flag name. Update documents to suggest
either the new pipeline or the new flag.

Next, we will have to migrate existing test and samples to use StableHLO
as the input format:
https://github.com/openxla/iree/issues/13869.
