Merge bitcoin/bitcoin#28851: build: Patch Qt to handle minimum macOS version properly
05aca093819be276ac7d648472c6ed5c7d235cc5 build: Patch Qt to handle minimum macOS version properly (Hennadii Stepanov)

Pull request description:

  This PR is:
  - required to [switch](https://github.com/bitcoin/bitcoin/pull/28622) to macOS 14 SDK (Xcode 15).
  - an alternative to https://github.com/bitcoin/bitcoin/pull/28732 and https://github.com/bitcoin/bitcoin/pull/28775.

  Qt relies on the `__MAC_OS_X_VERSION_MIN_REQUIRED` macro, which is set in the `AvailabilityInternal.h` SDK header to
  the value provided by the Clang driver from the `-mmacos-version-min` / `-mmacosx-version-min` option.

  Xcode 12 SDK expects the OS-specific `__ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__` macro:
  ```c++
  #ifndef __MAC_OS_X_VERSION_MIN_REQUIRED
      #ifdef __ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__
          /* compiler for Mac OS X sets __ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__ */
          #define __MAC_OS_X_VERSION_MIN_REQUIRED __ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__
      #endif
  #endif /* __MAC_OS_X_VERSION_MIN_REQUIRED*/
  ```

  In the other hand, Xcode 15 SDK expects a general `__ENVIRONMENT_OS_VERSION_MIN_REQUIRED__` macro:
  ```c++
  #ifndef __MAC_OS_X_VERSION_MIN_REQUIRED
      #if defined(__has_builtin) && __has_builtin(__is_target_os)
          #if __is_target_os(macos)
              #define __MAC_OS_X_VERSION_MIN_REQUIRED __ENVIRONMENT_OS_VERSION_MIN_REQUIRED__
              #define __MAC_OS_X_VERSION_MAX_ALLOWED __MAC_14_0
          #endif
      #elif  __ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__
          #define __MAC_OS_X_VERSION_MIN_REQUIRED __ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__
          #define __MAC_OS_X_VERSION_MAX_ALLOWED __MAC_14_0
      #endif /*  __has_builtin(__is_target_os) && __is_target_os(macos) */
  #endif /* __MAC_OS_X_VERSION_MIN_REQUIRED */
  ```

  The latter macro is not provided by LLVM Clang until c8e2dd8c6f, which is available in Clang 17.

  The suggested patch makes Qt "borrow" the `__MAC_OS_X_VERSION_MIN_REQUIRED` value from `MAC_OS_X_VERSION_MIN_REQUIRED`, which is set in the `AvailabilityMacros.h` SDK header.
