script/sorttable: Fix some initialization problems
elf_mcount_loc and mcount_sort_thread definitions are not
initialized immediately within the function, which can cause
the judgment logic to use uninitialized values when the
initialization logic of subsequent code fails.

scripts: ftrace - move the sort-processing in ftrace_init
When the kernel starts, the initialization of ftrace takes
up a portion of the time (approximately 6~8ms) to sort mcount
addresses. We can save this time by moving mcount-sorting to
compile time.

scripts/sorttable: Implement build-time ORC unwind table sorting
The ORC unwinder has two tables: .orc_unwind_ip and .orc_unwind, which
need to be sorted for binary search. Previously this sorting was done
during bootup.
Sort them at build time to speed up booting.
Add the ORC tables sorting in a parallel build process to speed up the build.

scripts/sorttable: Rename 'sortextable' to 'sorttable'
Use a more generic name for additional table sorting usecases,
such as the upcoming ORC table sorting feature. This tool is
not tied to exception table sorting anymore.
No functional changes intended.
