Add ability to not round-trip uncached inference results through IRCode (#47137)
 
There's generally three reasons inference results end up uncached:
1. They come from typeinf_ext
2. We discover some validity limitation (generally due to recursion)
3. They are used for constant propagation

Currently, we convert all such inference results back to CodeInfo,
in case they come from 1. However, for inference results of kind 3,
the only thing we ever do with them is turn them back into IRCode
for inlining. This round-tripping through IRCode is quite wasteful.
Stop doing that. This PR is the minimal change to accomplish that
by marking those inference results that actually need to be converted
back (for case 1). This probably needs some tweaking for external
AbstractInterpreters, but let's make sure this works and has the
right performance first.

This commit just adds the capability, but doesn't turn it on
by default, since the performance for base didn't quite look
favorable yet.
