shiny/driver/mtldriver: add darwin/arm64 (macOS) support

The Objective-C BOOL type is defined as a signed char on on Intel-based
Mac computers, but on Apple silicon, it is defined as as a native bool.¹

This makes it hard to write portable Cgo code across darwin/amd64 and
darwin/arm64 ports. So, stop relying on it, and use the bool type from
<stdbool.h> instead.

Update to a newer version of the mtl package with a similar change.

Fixes golang/go#43221.
