  [MLIR][NVGPU] Add truncf and extf Ops (#199700)

This change adds the `extf` and `truncf` ops to the NVGPU dialect to
support floating-point conversion operations.

These ops support scalar and vector inputs and lower to the corresponding
NVVM ops after padding and chunking the input into `i32` registers.
