[AArch64][SVE] Add basic support for @llvm.masked.compressstore (#168350)
This patch adds SVE support for the `masked.compressstore` intrinsic via
the existing `VECTOR_COMPRESS` lowering and compressing the store mask
via `VECREDUCE_ADD`.

Currently, only `nxv4[i32|f32]` and `nxv2[i64|f64]` are directly
supported, with other types promoted to these, where possible.

This is done in preparation for LV support of this intrinsic, which is
currently being worked on in #140723.
