[CostModel][X86] Add truncate cost tests to cover all legal destination types
...
We were only testing costs for legal source vector element counts

[X86] Add exhaustive cost model testing for sext/zext for all vector types we reasonably support. Add cost model tests for truncating to vXi1.
...
Our sext/zext cost modeling was somewhat incomplete. And had no coverage for the fact that avx512bw v32i16/v64i8 types return a scalarization cost.
Truncates are a whole different mess because isTruncateFree is returning true for vectors when it shouldn't and that's the fall back for anything not in the tables.

[CostModel][X86] Add some specific cpu targets to the cost models
...
We're mostly testing with generic isa attributes, but PR36550 will require testing of specific target's scheduler models as well.
