  [mlir][math] Fix intrinsic conversions to LLVM for 0D-vector types (#141020)

`vector<t>` types are not compatible with the LLVM type system – with
the current approach employed within `LLVMTypeConverter`, they must be
explicitly converted into `vector<1xt>` when lowering. Employ this rule
within the conversion patterns for intrinsics that are handled directly
within `MathToLLVM`: `math.ctlz` `.cttz`, `.absi`, `.expm1`, `.log1p`,
`.rsqrt`, `.isnan`, `.isfinite`.

This change does not cover/test patterns that are based off
`VectorConvertToLLVMPattern` template from `LLVMCommon/VectorPattern.h`.
