lib: linux: Add find_bit from Linux ...
Add lib/find_bit.c and include/linux/find.h from Linux v6.19, trimmed
to include only the functions needed for ext4l: find_first_bit(),
find_first_zero_bit(), find_next_bit(), find_next_zero_bit() and
find_last_bit()
The following items are removed from the Linux originals:
- find.h: _and_bit, _andnot_bit, _or_bit, _nth_bit variants, wrap
functions, clump8 functions, big-endian support, most for_each_...
macros
- find_bit.c: Corresponding implementations, random.h include
Add wrapper functions matching sandbox's asm/bitops.h declarations
(int return type, void* addr) that call the _find_* implementations.
Build find_bit.o only for sandbox for now.
