Richard Smith 59c1d6ff39 Remove refine_inst_action and its splices. (#7769 )

This action was created to wrap any `MetaInstId` operand of an action
instruction. This served two purposes:

1) It had a special hook in `OperandIsDependent` to allow it to be
   performed while it had a dependent operand (the reference to the
   instruction in the generic).
2) It created a `specific_inst` so that the downstream action saw an
   instruction in the specific instead of one in the generic.

These are both replaced: the special case in `OperandIsDependent` for
`RefineInstAction` is replaced by a special case for `MetaInstId`s in
general, and the `SpecificInst` is now created as part of performing the
downstream action, rather than as a separate step carried out
beforehand.

This simplifies the produced SemIR and reduces the number of splices
significantly. It also prepares us to handle actions like
initialization, where we don't actually want to create `SpecificInst`s
immediately in the location where the action is performed, because they
actually belong somewhere else in the IR.
