Eric Biggers b0e04dde8e crypto/crc32[c]: register only "-lib" drivers 
For the "crc32" and "crc32c" shash algorithms, instead of registering
"*-generic" drivers as well as conditionally registering "*-$(ARCH)"
drivers, instead just register "*-lib" drivers.  These just use the
regular library functions crc32_le() and crc32c(), so they just do the
right thing and are fully accelerated when supported by the CPU.

This eliminates the need for the CRC library to export crc32_le_base()
and crc32c_base().  Separate commits make those static functions.

Since this commit removes the "crc32-generic" and "crc32c-generic"
driver names which crypto/testmgr.c expects to exist, update testmgr.c
accordingly.  This does mean that testmgr.c will no longer fuzz-test the
"generic" implementation against the "arch" implementation for crc32 and
crc32c, but this was redundant with crc_kunit anyway.

Besides the above, and btrfs_init_csum_hash() which the previous commit
fixed, no code appears to have been relying on the "crc32-generic" or
"crc32c-generic" driver names specifically.

btrfs does export the checksum name and checksum driver name in
/sys/fs/btrfs/$uuid/checksum.  This commit makes the driver name portion
of that file contain "crc32c-lib" instead of "crc32c-generic" or
"crc32c-$(ARCH)".  This should be fine, since in practice the purpose of
the driver name portion of this file seems to have been just to allow
users to manually check whether they needed to enable the optimized
CRC32C code.  This was needed only because of the bug in old kernels
where the optimized CRC32C code defaulted to off and even needed to be
explicitly added to the ramdisk to be used.  Now that it just works in
Linux 6.14 and later, there's no need for users to take any action and
the driver name portion of this is basically obsolete.  (Also, note that
the crc32c driver name already changed in 6.14.)
