[llvm] [bazel][mlir][test] Skip MathToXeVM when SPIRV is not enabled (PR #163491)

[Jordan Rupprecht via llvm-commits]

https://github.com/rupprecht created https://github.com/llvm/llvm-project/pull/163491

This passes buildkite CI, but fails downstream if the SPIRV target is not enabled.

This is needed after #162934
