  -----------
  [OMPIRBuilder] Support runtime number of teams and threads, and SPMD mode

This patch introduces a `TargetKernelRuntimeAttrs` structure to hold
host-evaluated `num_teams`, `thread_limit`, `num_threads` and trip count values
passed to the runtime kernel offloading call.

Additionally, kernel type information is used to influence target device code
generation and the `IsSPMD` flag is replaced by `ExecFlags`, which provide more
granularity.
