machine/arch-armv9: remove crc and sve tunes, they are mandatory

Browse Source 
As per the Arm ARM section A2.3.2, FEAT_CRC32 is mandatory in Armv8.1
onwards, so there's no need to have an explicit optional tune for it.

SVE (which was a choice here) and SVE2 (which was not) are both optional
with v9.0, but GCC's -march=armv9-a defaults to enabling both SVE and
SVE2 on the grounds that there are no implementations of Armv9 that
don't support SVE2.  This means there's no point having an explicit sve
feature as it's enabled out of the box.
