[OpenACC][CIR] Implement 'device_type' clause lowering for 'init'/'sh… (#135102)
…utdown'

This patch emits the lowering for 'device_type' on an 'init' or
'shutdown'. This one is fairly unique, as these directives have it as an
attribute, rather than as a component of the individual operands, like
the rest of the constructs.

So this patch implements the lowering as an attribute.

In order to do tis, a few refactorings had to happen: First, the
'emitOpenACCOp' functions needed to pick up th edirective kind/location
so that the NYI diagnostic could be reasonable.

Second, and most impactful, the `applyAttributes` function ends up
needing to encode some of the appertainment rules, thanks to the way the
OpenACC-MLIR operands get their attributes attached. Since they each use
a special function (rather than something that can be legalized at
runtime), the forms of 'setDefaultAttr' is only valid for some ops. SO
this patch uses some `if constexpr` and a small type-trait to help
legalize these.
