  [AArch64][SVE] Remove LD1/ST1 dependency on llvm.masked.load/store

Summary:
The SVE masked load and store intrinsics introduced in D76688 rely on
common llvm.masked.load/store nodes. This patch creates new ISD nodes
for LD1(S) & ST1 to remove this dependency.

Additionally, this adds support for sign & zero extending
loads and truncating stores.
