### Brief description

A number of Domain kernels still do not have effective OMP coverage, which is affecting performance.

These are low hanging things to help OMP performance.

Some have already been attempted, but do not appear to be giving us the expected performance boost.

We can try them with the new Transmute Local script

This would provide a small uplift in kernel runtime performance with OMP.

Furthermore for PSyclone 3.3.1 fix Transmute issues

Potentially explore further Transmute testing
