  Log Message:
  -----------
  [OpenMP][NFC] Add min/max threads/teams count into the KernelEnvironment (#70257)

The runtime needs to know about the acceptable launch bounds, especially
if the compiler (middle- or backend) assumed those bounds. While this
patch does not yet inform the runtime, it stores the bounds in a place
that can/will be accessed and is associated with the kernel.
