feat: use CGPreflightScreenCaptureAccess API for ScreenAuthStatus

[quanglam2807]

Based on this: https://stackoverflow.com/a/65423834/5522263, Apple has an official API to get Screen Auth permission status: CGPreflightScreenCaptureAccess: https://developer.apple.com/documentation/coregraphics/3656523-cgpreflightscreencaptureaccess

I've tested this with Electron 11.1.1 + macOS 11 and it worked perfectly.

Hey thanks - this is great. Lint and test CI are failing right now because of missing LDFLAGS - when we add CoreGraphics we also need to add that library to binding.gyp.

Once that's fixed up we can get this landed!

Thank you, @codebytere. I don't know what happens but CI keeps returning ../permissions.mm:168:9: error: use of undeclared identifier 'CGPreflightScreenCaptureAccess' while node-gyp` compiles successfully on my local environment.

@quanglam2807 i'll take a closer look soon 🤔

Any progress made on this?

I'm curious if the CI is running a different version of xcode or using command line tools instead.
Available software in macos node in github workflows:
https://github.com/actions/virtual-environments/blob/main/images/macos/macos-11.0-Readme.md

Maybe the CI SDK version need to be synced with your dev environment @quanglam2807?
A potential way to force a different MacOS SDK via github workflow and to test this hypothesis:

env:
  DEVELOPER_DIR: /Applications/Xcode_12.4.app/Contents/Developer

@quanglam2807 would you mind rebasing this? I can take it over and try @mmaietta's suggestion above if you'd like as well

Thank you for checking this, @codebytere @mmaietta

I managed to fix the problem partially by using newer SDK. But I don't know how to fix:

dyld: lazy symbol binding failed: Symbol not found: _CGPreflightScreenCaptureAccess
  Referenced from: /Users/runner/work/node-mac-permissions/node-mac-permissions/build/Release/permissions.node
  Expected in: /System/Library/Frameworks/CoreGraphics.framework/Versions/A/CoreGraphics

This is odd. If the API is supported in macOS 10.15+, then I suppose the symbol must be in the system's framework?

@quanglam2807 looks like: lwouis/alt-tab-macos#704 (comment)

[quanglam2807]

It seems like the API is added in Bug Sur. So Apple provides wrong documentation?

I can modify the PR to only use the new API in macOS 11+ and retain the old code for older versions. Would that work?

@quanglam2807 sounds great to me! Thanks for being patient with this PR - appreciated 🙇🏻‍♀️
