objtool/klp: Extricate checksum calculation from validate_branch()
In preparation for porting the checksum code to other arches, make its
functionality independent from the CFG reverse engineering code.
Move it into a standalone calculate_checksums() function which iterates
all functions and instructions directly, rather than being called inline
from do_validate_branch().
Since checksum_update_insn() is no longer called during CFG traversal,
it needs to manually iterate the alternatives.
