  [SPIRV] Add a `SPIRVTypeInst` type with some guardrails (#179947)

The idea behind this PR is to propose a type that we can deploy
gradually to add some guardrails and enforce invariants in the SPIRV
backend.

The PR has 3 commits:
* A first commit where the `SPIRVTypeInst` type is proposed. It's just a
wrapper around `MachineInstr` that adds an assert to check that a
`SPIRVTypeInst` defines a register with the type register class.
* A second commit that shows how the migration could look like for a
single function.
* A third commit that motivates why: we have a `SPIRVType *TypeInst`
that never defines a type in a function whose intention looks very
confusing.
