Mosa.DeviceDriver: various improvements

[AnErrupTion]

This PR focuses on various improvements (like bug fixes) throughout the Mosa.DeviceDriver project. The following changes were done:

• Put references to links in comments after the namespace
• In PCIController, the Definitions region was removed since it only contained 1 field
• The Mosa.Runtime.Pointer struct was made readonly to fix some potential struct copying for ACPI structs
• In VMwareSVGA2:
  • Private fields were put after the public frame buffer field for consistency
  • The private vramSize field has been removed since it was unused
• In ACPIDriver:
  • Variables and private fields were renamed to better match naming conventions
  • Some if conditions were inverted to reduce nesting
  • The Setup() function was removed and the code was put in the Initialize() function
• In the ACPI sister structs:
  • The readonly modifier was added on a per-struct basis
  • Made the Size field const in each
• Added DeviceBusType.None and GenericDeviceDriverRegistryEntry to deal with ACPI (as it's neither an ISA nor a PCI driver)
• In IDEController, the Open() function was moved into the IDiskControllerDevice region for more consistency
• Runtime device names were changed to better fit naming conventions and their job (e.g. ISA-BUS => ISABus, PCI => PCIController, etc...)
• The code to trigger an ACPI reboot by writing to the PCI configuration space was removed since it never even worked in the first place
• The PS/2 mouse code was almost entirely reworked for better code readability and slightly better performance as well
• The US keyboard map was also reworked to fix bugs mainly related to modifiers
