  [ARM] Add instruction selection for strict FP (#160696)

This consists of marking the various strict opcodes as legal, and
adjusting instruction selection patterns so that 'op' is 'any_op'. The
changes are similar to those in D114946 for AArch64.

Custom lowering and promotion are set for some FP16 strict ops to work
correctly.

This PR is part of the work on adding strict FP support in ARM, which
was previously discussed in #137101.
