  -----------
  [mlir][OpenACC] Restrict implicit data to compute constructs (#222759)

acc.kernel_environment contains host-side preparation around an outlined
compute region; it is not itself an OpenACC compute construct. Treating
all of its live-ins as implicit device mappings can map
compiler-generated host operations and assign them kernels-style copy
semantics.

Limit ACCImplicitData to parallel, kernels, and serial. In particular,
do not process kernel_environment or the lowered compute_region form.
