[GlobalISel] Fix bitcast fewerElements with scalar narrow types. (#153364)
For a <8 x i32> -> <2 x i128> bitcast, that under aarch64 is split into
two halfs, the scalar i128 remainder was causing problems, causing a
crash with invalid vector types. This makes sure they are handled
correctly in fewerElementsBitcast.

++ 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.
