`bug49334.cpp` has one issue that causes flaky result reported in #53730.
The root cause is `BlockedC` is never initialized but in `BlockMatMul_TargetNowait`
it is directly read and written (via `+=`). Fixes#53730.

This patch adds a new target to the OpenMP CPU offloading tests. This
tests the usage of the new driver for CPU offloading. If this all works
then we can move to transition to the new driver as the default.
Depends on D119613

`bug49334.cpp` directly uses `!=` to compare two floating point values,
which is almost wrong.

This patch completely removes the old OpenMP device runtime. Previously,
the old runtime had the prefix `libomptarget-new-` and the old runtime
was simply called `libomptarget-`. This patch makes the formerly new
runtime the only runtime available. The entire project has been deleted,
and all references to the `libomptarget-new` runtime has been replaced
with `libomptarget-`.

Passes same tests as the current deviceRTL. Includes cmake change from D111987.
CI is showing a different set of pass/fails to local, committing this
without the tests enabled by default while debugging that difference.

`bug49334.cpp` cannot detect data race in `libomptarget` efficiently. It
is reported that with `N = 256` and `BS = 16`, the data race can be reproduced
more steadily. The next coming pathces will fix it so this patch is expected to
fail now.

This patch fuses the RUN lines for most libomptarget tests. The previous patch
D101315 created separate test targets for each supported offloading triple.
This patch updates the RUN lines in libomptarget tests to use a generic run
line independent of the offloading target selected for the lit instance.
In cases, where no RUN line was defined for a specific offloading target,
the corresponding target is declared as XFAIL. If it turns out that a test
actually supports the target, the XFAIL line can be removed.

PR#49334 reports a crash when offloading to x86_64 with `target nowait`,
which is caused by referencing a nullptr. The root cause of the issue is, when
pushing a hidden helper task in `__kmp_push_task`, it also maps the gtid to its
shadow gtid, which is wrong.
