[metal-cpp] Update to macOS14.2_iOS17.2

[luncliff]

Changes

The port is too old for the latest Apple platform SDKs.

• Use the SDK names for version-string.
  The previous style, version-date didn't provide a proper description of the port.
• Install usage. Provide a link to GitHub repository https://github.com/bkaradzic/metal-cpp
• Remove "supports" constraint because the project is header-only.
