[OPENMP]Do not use OMP_MAP_TARGET_PARAM for data movement directives.

OMP_MAP_TARGET_PARAM flag is used to mark the data that shoud be passed
as arguments to the target kernels, nothing else. But the compiler still
marks the data with OMP_MAP_TARGET_PARAM flags even if the data is
passed to the data movement directives, like target data, target update
etc. This flag is just ignored for this directives and the compiler does
not need to emit it.
