  [mlir] Reduce generated assembly printer compile time

Use fixed arrays for statically elided attributes and combine leading spaces
with literals. Initialize fixed elisions together when runtime elision is
needed; in strict properties mode, print discardable attributes directly.

Move common operand printing out of generated call sites and emit sliced
operand getters to reduce optimizer work in large printers.

For omp.target, the original patch reduced optimized print IR from 3,893 to
2,667 instructions. Its printing benchmark was 2.1% slower.
