switch macos clipboard crate

This cleans up the `cargo audit` output on linux because the `clipboard`
crate (which hasn't been updated in 3 years) depends on xcb=0.8.2
which is flagged by cargo audit.

We don't use `clipboard` on any platform except macos

This commit switches to the `clipboard_macos` crate; that appears to
use a copy and paste of the macos specific code from the `clipboard`
crate, so this shouldn't have any change in functionality.
