Fix using trunk version on mac

Overriding the metal version in the workspace Cargo.toml using a patch
section does not work for projects building against the trunk version:

wgpu = { git = "https://github.com/gfx-rs/wgpu", branch = "trunk" }

Instead specify the metal dependencies only once in wgpu-hal.
