Upgrade Arm GNU toolchain and GCC to version 13

[wassr]

Fixes #49

[wassr]

Upgrades:

• Arm GNU toolchain 12.2 → 13.3
• gcc/g++ 12 → 13
• Catch2 3.1.0 → 3.3.0
• clang-tidy-cache

Catch2 needed to be upgraded to work with GCC 13 and gcov was also fixed to its version from GCC 13 to avoid ambiguous versions.

Currently, throws errors when building COBC SW.

IWYU only added support for Clang 18 in version 0.22.

This PR and the related issue are only about upgrading the Arm GNU toolchain and GCC, not about the clang tools, so I reset that part.

The build errors are not from GCC but from clang-tidy, and can be fixed by adding the command line option --extra-arg=-fsized-deallocation to clang-tidy.
