    Use 'GOMP_MAP_VARS_TARGET' for OpenACC compute constructs [PR90596]

    Thereby considerably simplify the device plugins'
'GOMP_OFFLOAD_openacc_exec',
    'GOMP_OFFLOAD_openacc_async_exec' functions: in terms of lines of code, but
in
    particular conceptually: no more device memory allocation, host to device
data
    copying, device memory deallocation -- 'GOMP_MAP_VARS_TARGET' does all that
for
    us.

    This depends on commit 2b2340e236c0bba8aaca358ea25a5accd8249fbd
    "Allow libgomp 'cbuf' buffering with OpenACC 'async' for 'ephemeral' data",
    where I said that "a use will emerge later", which is this one here.
