[AArch64] Don't use tbl lowering if ZExt can be folded into user.
If the ZExt can be lowered to a single ZExt to the next power-of-2 and
the remaining ZExt folded into the user, don't use tbl lowering.

Fixes #62620.

++ SVE CodeGen Warnings ++

When the WARN check lines fail in the SVE codegen tests it most likely means you
have introduced a warning due to:
1. Adding an invalid call to VectorType::getNumElements() or EVT::getVectorNumElements()
   when the type is a scalable vector.
2. Relying upon an implicit cast conversion from TypeSize to uint64_t.

For generic code, please modify your code to work with ElementCount and TypeSize directly.
For target-specific code that only deals with fixed-width vectors, use the fixed-size interfaces.
Please refer to the code where those functions live for more details.
