Merge bitcoin/bitcoin#33489: build: Drop support for EOL macOS 13

1aaaaa078b fuzz: Drop unused workaround after Apple-Clang bump (MarcoFalke)
fadad7a494 Drop support for EOL macOS 13 (MarcoFalke)

Pull request description:

  Now that macOS 13 is EOL (https://en.wikipedia.org/wiki/MacOS_Ventura), it seems odd to still support it.

  (macOS Ventura 13.7.8 received its final security update on 20 Aug 2025: https://support.apple.com/en-us/100100)

  This patch will only be released in version 31.x, another 6 months out from now.

  So:

  * Update the depends build and release note template to drop EOL macOS 13.
  * As a result, update the earliest Xcode to version 16 in CI.
  * Also, bump the macOS CI runner to version 15, to avoid issues when version 14 will be at its EOL in about 1 year.

  This also allows to drop a small workaround in the fuzz tests and unlocks libcpp hardening (https://github.com/bitcoin/bitcoin/pull/33462)
