Add GPU driver interrupt handling, Intel GPU PCI config, and display improvements

Browse Source 
AMD display driver: expanded DCN pipeline setup with plane/controller/stream mapping.
Intel driver: cleaned up module structure.
New interrupt module for MSI-X vector management across GPU drivers.
PCID config endpoint patch and Intel GPU TOML for automatic driver spawning.
Expanded redox_stubs with additional kernel API shims.
