companion_libs: Make picolibc build compatible with 1.8.10
Picolibc 1.8.10 reworked the configuration option for single/multi
thread support and removed some unused options for exit handler
support.
Map LIBC_PICOLIBC_MULTITHREAD to the new single-thread option or the old
newlib-retargetable-locking+newlib-multithread options depending on whether
the picolibc version knows about the single-thread option.
Remove support for newlib-register-fini, newlib-atexit-dynamic-alloc,
newlib-global-atexit and lite-exit options as all of those relate to
the legacy exit handler code. There hasn't ever been any way to enable
this using crosstool-ng, so none of these options have ever done
anything.
The help strings for each of of the unused configuration variables
have been updated.
