[metal] Use objc2-metal

commit 0a1ce66
Author: Mads Marquart <[email protected]>
Date:   Fri Apr 25 22:01:53 2025 +0200

    Use normal objc2 naming scheme

commit 35a9525
Author: Mads Marquart <[email protected]>
Date:   Tue Apr 29 14:24:41 2025 +0200

    Use `objc2-metal` with `metal` naming scheme

    To keep the diff smaller and easier to review, this uses a temporary
    fork of `objc2-metal` and `objc2-quartz-core` whose methods use the
    naming scheme of the `metal` crate.

    One particular difficult part with this is that the `metal` crate has
    several methods where the order of the arguments are swapped relative
    to the corresponding Objective-C methods.

    This includes most perilously (since these have both an offset and an
    index argument, both of which are integers):
    - `set_bytes`
    - `set_vertex_bytes`
    - `set_fragment_bytes`
    - `set_buffer`
    - `set_vertex_buffer`
    - `set_fragment_buffer`
    - `set_threadgroup_memory_length`

    But also:
    - `set_vertex_texture`
    - `set_fragment_texture`
    - `set_sampler_state`
    - `set_vertex_sampler_state`
    - `set_fragment_sampler_state`

    Another noteworthy thing to mention is that `objc2-metal` does not (yet)
    provide a fallback for MTLCopyAllDevices, so we have to do that
    ourselves:
