[Inline][PGO] After inline, update InvokeInst profile counts in caller and cloned callee (#83809)

A related change is https://reviews.llvm.org/D133121, which correctly
preserves both branch weights and value profiles for invoke instruction.
* If the branch weight of the `invokeinst` specifies taken / not-taken branches, there is no scale.
