  [clang][flang][omp] Always generate a kernel environment (#223772)

Currently OpenMP doesn't generate a Kernel Enviroment for host kernels
or ompx_bare kernels. This causes the runtime to have special handling
for this cases.

This patch ensures that a Kernel Environment is always generated which
will allow to simplify the RTL handling.

Done mostly by Claude.
