Meta+Documentation: Require Xcode 14.3 or Clang 14 for the host compiler

Browse source 
There have been multiple reports of Xcode 14.0 (based on upstream LLVM
14) segfaulting when compiling `LibCore/Process.cpp`. Let's require
Xcode 14.3, which is a known good version based on LLVM 15.

Note that Xcode 14.3 requires macOS Ventura, so users of Monterey or
older are expected to get Homebrew Clang instead.

Homebrew Clang 13 also suffers from the same crash. Although I have not
tested on Linux, the backtrace points to the middle-end, so x86_64 is
also likely to be affected. LLVM 14 was released 14 months ago, so it's
not an unreasonable requirement.

A host compiler that supports C++20 features is required for building host tools, the newer the better. Tested versions include gcc-12 and clang-13.
A host compiler that supports C++20 features is required for building host tools, the newer the better. Tested versions include gcc-12 and clang-14.
On Ubuntu gcc-12 is available in the repositories of 22.04 (Jammy) and later.
If you are running an older version, you will either need to upgrade, or find an alternative installation source.
