perf: arm_spe: Add support for FEAT_SPE_EFT extended filtering

FEAT_SPE_EFT (optional from Armv9.4) adds mask bits for the existing
load, store and branch filters. It also adds two new filter bits for
SIMD and floating point with their own associated mask bits. The current
filters only allow OR filtering on samples that are load OR store etc,
and the new mask bits allow setting part of the filter to an AND, for
example filtering samples that are store AND SIMD. With mask bits set to
0, the OR behavior is preserved, so the unless any masks are explicitly
set old filters will behave the same.

Add them all and make them behave the same way as existing format bits,
hidden and return EOPNOTSUPP if set when the feature doesn't exist.
