Various fixes for build environments (Flang, Windows) and XML

Changed

• Add an enclosing <testsuites> element an xml version/encoding element in the funit xml output. Makes the output readable by more CI systems (Jenkins, GitLab-CI).
• Change CMake from using PARENT_SCOPE to CACHE INTERNAL as it seems in some setups using
  pFUnit via FetchContent the former does not work as expected.
• Update some COMMENT lines in functions with double-quotes to avoid warnings

Fixed

• Fix parser on Windows for paths with different drive letters
• Updates for CMake versions newer than 3.30.
• Update NVHPC CI (build only)
• Fix CMake for LLVM Flang
• Update object library dependency handling (see #495)

Full Changelog: v4.12.0...v4.13.0

Update minimum required CMake version

Changed

• Updated minimum required CMake version to 3.12 in tests/ to match main CMakeLists.txt and documentation. Previously set to 3.0 which is now deprecated and was causing build issues.

GFortran workaround

Fixed

• Workaround for gfortran 13/14 on Ubuntu. Failure does not show on other fla
  vors of Linux no macos.

Misc updates (support for Flang)

Changed

• Updated submodule for fArgParse
• Update CI to have gfortran-10 and gfortran-11 only on ubuntu-22.04
• Update CI NVIDIA to NVHPC 24.7
• Add Flang to CI

Migrated to use v2 interfaces from gFTL

Changed

• Updated pFUnit to use v2 template interfaces
• Added -quiet flag for NAG Fortran
• Remove macos-11 from GitHub Actions, add macos-12 and gfortran-14 to Ubuntu 24.04
• Updated fArgParse to v1.8.0

Added

• LLVMFlang compiler support

Fixed

• Fixes some ctest failures

Port to Fujitsu and a few bug fixes

Added

• Fujitsu compiler support

Fixed

• This fixes a small CMake bug which can lead to posix_predefined.x being built in the wrong build subdirectory when CMAKE_RUNTIME_OUTPUT_DIRECTORY is set*.
• Missing implementation of assertIsFinite_real80(). Apparently undetected until recent attempt to port to flang.
• Made support for REAL128 optional. (Port to nvfortran)

Changed

• Updated the CI to use Intel LLVM compilers
• Removed obsolete documentation

Update submodule for fArgParse

Changed

• Updated submodule for fArgparse [v1.6.0]

Workarounds for gfortran 13.2

Fixed

• Several workarounds added to enable building with gfortran 13.2. Polymorphic assignment is broken, and must be replaced by ALLOCATE(obj,source=...). But apparently not everywhere?
• Add -check nouninit for Intel LLVM to work around ifx bug.

Changed

• Updated CI to remove gcc-9 from macOS11 and add gcc-12

Minor bug fixes

Fixed

• Fixed cmake issue where target "pfunit-mpi-defines" is defined more than once
• Missing variable declaration in parameterized test case boiler plate code.
