[TailDuplicator] Add maximum predecessors and successors to consider tail duplicating blocks (#78582)

Fixes #78578.

Duplicating a BB which has both multiple predecessors and successors
will result in a complex CFG and also may cause huge amount of PHI
nodes. See
https://github.com/llvm/llvm-project/issues/78578#issuecomment-1962363580
for a detailed description of the limit.
