[SVE] Add get_active_lane_mask builtin (#16965)

Adds a `get_active_lane_mask` builtin and lowering to
`llvm.get.active.lane.mask` intrinsic. This will be used in subsequent
patches for expressing predicated buffer loads/stores in TIR. Further
information can be found in the [RFC](https://github.com/apache/tvm-rfcs/blob/main/rfcs/0104-scalable-vectors-in-tir.md#predication).
