This is a respin of my patchset implementing both the `dispatch` construct and
the `adjust_args` clause to the `declare variant` directive. The previous
submission can be found there:
https://gcc.gnu.org/pipermail/gcc-patches/2024-July/657151.html.
Beside being rebased, this new iteration has the following changes:
* Remove `need_device_ptr` as pseudo-trait set selector and pass `adjust_args`
list as attribute to the base function. This also ensures that the list will
survive multiple declarations;
* OpenMP 5.1 mandated that each dispatch construct should generate an explicit
task. This requirement has been lifted in 5.2, so we removed it;
* As a result, some clauses are now handled differently: nowait has no effect,
depend is moved to a taskwait construct and the default-device ICV has to be
restored at the end of the dispatch region;
* Update test cases.
