sm8750-common: Downgrade to ARMv8.2-A.

Browse Source 
Clang assumes that ARMv9-A chips always implement SVE2,
but SM8750 (Snapdragon 8 Elite) does not, so it broke when
aosp/2292699 made the "armv9-a" variant actually set ARMv9-A.
Before, it was actually using ARMv8.2-A with some additional
flags due to a variety of SVE-specific toolchain and
configuration issues that are fixed now.

Downgrade SM8750 to the "ARMv8.2-A with dotprod extension"
arch variant, which is the closest to the previous
configuration, until we can add a proper "ARMv9-A without SVE"
arch variant.
