  [offload][OpenMP] Add strict flag for blocks and threads in kernel arguments (#199483)

Until now, strict behavior in the number of threads and blocks has been
applied only when the kernel is in bare mode. When this mode is enabled,
the values passed in UserNumBlocks and UserThreadLimit are not adjusted
and are the definitive values used to launch the kernel. This commit
detaches the strictness from the kernel mode.

This is going to be used by the kernel replay tool. Additionally, it
starts clearing the path for the upcoming OpenMP dims modifier, used to
configure multidimensional teams and leagues, which will include
strictness choices for teams and threads.

All the bare kernels must indicate strict behavior. Asserts are added to
check this condition.
