Add support for aarch64-apple-darwin

Please consider add support for Apple M1

It appears to work when building locally in my experience. But if you are cross compiling (e.g. in CI), you'll need to set the JEMALLOC_SYS_WITH_LG_PAGE environment variable to 14 or you will get an error like "<jemalloc>: Unsupported system page size" at runtime.

Should this be set automatically when building for macOS aarch64 like done here for iOS?

jemallocator/jemalloc-sys/build.rs

Lines 237 to 241 in c27a859

	if target.contains("ios") {
	// newer iOS deviced have 16kb page sizes:
	// closed: https://github.com/gnzlbg/jemallocator/issues/68
	cmd.arg("--with-lg-page=14");
	}

Is this issue solved? I still have the m1 compiling error (not supported).

Thanks,

We've hit the same problem in ruff (astral-sh/ruff#3791 (comment)). Would it be possible to make JEMALLOC_SYS_WITH_LG_PAGE=16 the default when cross compiling?
