Merge libdispatch-1462.0.4

[AZero13]

This took a bit of work to ensure every change that happened following the last merge was preserved, but I was eventually able to do it.

This brings libdispatch on par with macOS Sonoma!

Thank you for trying to keep this repo up-to-date!

I just wanted to note that there are a couple errors when trying to build this branch on Android or Windows (and possibly other non-Apple platforms) due to new references to Apple-specific headers/defines:

• workgroup_base.h:15:10: fatal error: 'mach/port.h' file not found
• object.h:278:1: error: unknown type name 'OS_ASSUME_PTR_ABI_SINGLE_BEGIN'

And on Android there’s also this error:

libdispatch-android-build.txt contains the full build instructions and logs for an Android build. Not sure if this is something that would have to be sorted out before a merge.

I'm working on it and looking into it!
