Sometimes it is necessary to group patchable function entrypoint records in distinct linker sections. This is the case for some bpf functions within the linux kernel which shouldn't be visible to ftrace. Extend `-Zpatchable-function-entry` to accept an argument of the form `prefix_nops,total_nops,record_section`, which places all entry record into a user specified section. Likewise, extend the `patchable_function_entry` attribute to accept an optional `section="name"` option to place a function into a specific section. This is made possible by llvm attribute `patchable-function-entry-section` added in llvm 21.

error: incorrect value `1,2` for unstable option `patchable-function-entry` - a comma separated list of (prefix_nops,total_nops,section_name), (prefix_nops,total_nops), or (total_nops). Where prefix_nops <= total_nops where 0 < total_nops <= 255 and prefix_nops <= total_nops was expected
