[msan] Apply handleVectorReduceIntrinsic to max/min vector instructions (#129819)
Changes the handling of:
- llvm.aarch64.neon.smaxv
- llvm.aarch64.neon.sminv
- llvm.aarch64.neon.umaxv
- llvm.aarch64.neon.uminv
- llvm.vector.reduce.smax
- llvm.vector.reduce.smin
- llvm.vector.reduce.umax
- llvm.vector.reduce.umin
- llvm.vector.reduce.fmax
- llvm.vector.reduce.fmin
from the default strict handling (visitInstruction) to
handleVectorReduceIntrinsic.

Also adds a parameter to handleVectorReduceIntrinsic to specify whether
the return type must match the elements of the vector.

Updates the tests from https://github.com/llvm/llvm-project/pull/129741,
