[GlobalISel] Add `G_EXTRACT_VECTOR_ELT` for `computeKnownBits` (#164825)
The code is ported from `SelectionDAG::computeKnownBits`.
As a result of adding `G_EXTRACT_VECTOR_ELT` to `GlobalISel`, the code
generated for some of the existing regression tests changes. The changes
in `neon-extadd-extract.ll` and `knownbits-buildvector.mir` look good to
me. Though I'm struggling to understand the diff in `sdiv.i64.ll`. Is
there a test that checks if the generated amdgcn produces the correct
result? Or tools that help with executing it (I do have an AMD GPU)?
**Edit**: Related to #150515
