JIT: remove incremental ref count updates (#19345)
Remove almost all of the code in the jit that tries to maintain local ref
counts incrementally. Also remove `lvaSortAgain` and related machinery.
Explicitly sort locals before post-lower-liveness when optimizing to get the
best set of tracked locals.
Explicitly recount after post-lower liveness to get accurate counts after
dead stores. This can lead to tracked unreferenced arguments; tolerate this
during codegen.
