LOG: [mlir][Bufferization] Split the dialect declaration (NFC) (#222859)

Introduce a self-contained dialect declaration and use it in four
consumers that do not need the generated operation umbrella.

Across three controlled serial rebuilds of the affected TUs, median
instructions fell from 97.470B to 94.887B (-2.650%) and median wall time
fell from 15.20s to 14.70s (-3.289%). Three -j16 runs confirmed a 2.623%
reduction in instructions, with wall time improving 0.722% on the
parallel critical path.
