target/ppc: rework vmul{e,o}{s,u}{b,h,w} instructions to use Vsr* macros

Browse source 
The current implementations make use of the endian-specific macros HI_IDX and
LO_IDX directly to calculate array offsets.

Rework the implementation to use the Vsr* macros so that these per-endian
references can be removed.
