refactor(sve): move sve operations to a lib routine

This patch moves the SVE subtract operation to a common sve library
routine and takes a callback function that does the world switch while
SVE operations are done in a loop.

The callback is invoked after z0, z1 vectors are loaded and before
the calculated results are stored back in the vector registers.

This refactoring later helps to use this function to do context switch
from NS to Secure world or from NS to Realm world based on the
callback type.

This patch also moves the SVE fill vector registers, read vector
registers to a common sve library routine.
