[llvm-profgen][CSSPGO] On-demand function size computation for preinliner

Similar to https://reviews.llvm.org/D110465, we can compute function size on-demand for the functions that's hit by samples.

Here we leverage the raw range samples' address to compute a set of sample hit function. Then `BinarySizeContextTracker` just works on those function range for the size.
