[CUDA] Move CUDA to new driver by default (#122312)
Summary: This patch updates the --offload-new-driver flag to be default for CUDA. This mostly just required updating a lot of tests to use the old format. I tried to update them where possible, but some were directly checking the old format. https://discourse.llvm.org/t/rfc-use-the-new-offloding-driver-for-cuda-and-hip-compilation-by-default/77468/18

10831083
- Clang now supports CUDA SDK up to 12.6
10841084
- Added support for sm_100
10851085
- Added support for `__grid_constant__` attribute.
1086+
- CUDA now uses the new offloading driver by default. The new driver supports
1087+
device-side LTO, interoperability with OpenMP and other languages, and native ``-fgpu-rdc``
1088+
support with static libraries. The old behavior can be returned using the
1089+
``--no-offload-new-driver`` flag. The binary format is no longer compatible
1090+
with the NVIDIA compiler's RDC-mode support. More information can be found at:
