Building and testing the MySQL 26.7.0 early access build on macOS

Oracle released the MySQL 26.7.0 community early access build. I did my part in my usual way (previously: 9.7.0 in the early access series; 8.0.46 / 8.4.9 / 9.7.0 in the main series).

Build

As has been the rule for a while now, there is no need to use the bundled third-party libraries, as the Homebrew versions work. The current Xcode (26.6) builds the 26.7.0 early access build fine in all tested (debug, release, and debug + sanitizers) configurations. Homebrew LLVM builds continue to be broken: bug #120717 and bug #119246.
