  -----------
  [mlir][NVVM] Split out the dialect declaration to improve build time (NFC) (#222783)

Move NVVMDialect to a self-contained declaration header and use it in
five consumers that do not need generated NVVM operations.

Across three controlled rebuilds of the affected TUs, median
instructions fell from 215.791B to 161.538B (-25.141%) and median wall
time fell from 33.40s to 24.66s (-26.168%).
