  -----------
  [BOLT] Add support for Linux kernel static calls table (#82072)

Static calls are calls that are getting patched during runtime. Hence,
for every such call the kernel runtime needs the location of the call or
jmp instruction that will be patched. Instruction locations together
with a corresponding key are stored in the static call site table. As
BOLT rewrites these instructions it needs to update the table.
