Implement Alpha Support for Nvidia Web Drivers

[khronokernel]

This PR's goal is to implement basic Nvidia Web Driver support for Big Sur and Monterey. These patches are highly experimental, and do not support many features expected of the Web Drivers from High Sierra

This build's main draw back is relying on the non-Metal stack, thus having the same issues as non-Metal graphics cards we see today. See issue 108 for more information.

To use this build, you'll need the following:

• GPU Device ID listed in pci_ids.py under Maxwell or Pascal
• WhateverGreen.kext installed
• Library Validation Disabled
  • One of:
    • Boot-arg: amfi_get_out_of_my_way=0x1
    • Kernel Patch: _cs_require_lv patch
• Forced Compatibility via WhateverGreen
  • One of:
    • Boot-arg: ngfxcompat=1
    • DeviceProperty: force-compat | Data | 01000000
• Forced OpenGL rendering
  • One of:
    • Boot-arg: ngfxgl=1
    • DeviceProperty: disable-metal | Data | 01000000
• Enable Web Drivers
  • Boot-arg: nvda_drv_vrl=1
• SIP Lowered to 0xa03
  • CSR_ALLOW_UNTRUSTED_KEXTS
  • CSR_ALLOW_UNRESTRICTED_FS
  • CSR_ALLOW_UNAPPROVED_KEXTS
  • CSR_ALLOW_UNAUTHENTICATED_ROOT

As warned before, drivers are highly experimental. This PR should only be used by developers and not the general public.
