* add support for UEFI time and UEFI events; fix STOP \n -> \r\n conversion
* make it so both scheduler=none and scheduler=tasks works
* address pr comments
- Renamed/shared the amd64 Win64 ABI task stack Go file for both Windows and UEFI.
- Deleted the duplicate UEFI task stack Go file and old Windows-suffixed Go file.
- Added task_stack_amd64_windows.S unconditionally to targets/uefi-amd64.json.
- Removed the UEFI ExtraFiles() special case from compileopts/config.go.
- Added a scheduler.none tinygo_task_exit stub.
- Removed the custom UEFI sleep override so normal scheduler sleep queue is used.
* revert back to simpler return value for ExtraFiles()
* create uefi specific tasks_none file
* remove unused sleepSchedulerCustom stuff
* add back the uefi tag
* lib: restore macos-minimal-sdk pointer
