Version 0.8.1 CUDA 12.x compatibility improvements & minor fixes

Changes since v0.8.0:

CUDA 12.x compatibility

• #711 : Added preliminary information regarding Blackwell cards and micro-architecture
  *#701 : The --version-ident compilation option to NVRTC was dropped in CUDA 12.2; this is now respected by the wrappers and the option is not exposed for 12.2 and newer versions of CUDA.
• #702 : Fixed handling of --version-ident (we had a spacing issue)
• #635, #701 : Added support for the --fdevice_syntax_only and --minimal options for NVRTC compilation

Changes to the unique_span & unique_region classes

• #703 : unique_span<T>::swap() now correctly swaps the deleters as well
• #713 : Move constructor and assignment operator of unique_region_t
• #702 : Fixed a typo when passing the --no-source-include option to NVRTC
• #719: Removed redundant cast operations from unique_span<T>

Bug fixes

• #706 : Made context_t::flags() non-virtual
• #710 : Fixed the comparison operators for launch configurations
• #709 : Span-to-C-array copy no longer ignoring the designated stream
• #708 : Avoiding infinite recursion in link_t::add_file()

Build & installation

• #717: Creating possibly-missing CUDAToolkit targets in installed config files, so that library targets can rely on them: nvfatbin, nvfatbin_static and cufilt.

Other changes

• #704 : Limited the clang warning flags (no -pedantic) to avoid warnings we can't resolve
• #705 : Made some methods of library_t be const
• #721 : device::proprties_t::max_in_flight_threads_on_device() now returns an unsigned (rather than unsigned long long)

Example programs

• #720 : Avoiding suspicious numeric conversions in the example programs (mostly inherited from NVIDIA, tsk tsk tsk)
• #722: In simpleCudaGraphs, when using stream capture, now enqueueing the correct, existing event rather than an anonymous transient event
• Now compiling the example programs with more warning flags on.
