[BOLT] Add split function support for the Linux kernel (#90541)

While rewriting the Linux kernel, we try to fit optimized functions into
their original boundaries. When a function becomes larger, we skip it
during the rewrite and end up with less than optimal code layout. To
overcome that issue, add support for --split-function option so that hot
part of the function could be fit into the original space. The cold part
should go to reserved space in the binary.
