[MLIR][OpenMP] NFC: Sort clauses alphabetically (1/2)

[skatrak]

This patch sorts the clause lists for the following OpenMP operations:

• omp.parallel
• omp.teams
• omp.sections
• omp.wsloop
• omp.distribute
• omp.task

This change results in the reordering of operation arguments, so impacted unit tests are updated accordingly.

LGTM

[tblah]

Thanks. It is really good to see all of these code quality and maintainability improvements you have been doing. The combined impact is large.
