[lib][uefi] Move certain UEFI headers to public include dir This allows other components to reference basic UEFI types. Now different platforms can provide their own override for certain UEFI protocols. To keep good include structure, all public headers are put under include/uefi. 2025-05-29 11:01:37 -07:00			`#include <uefi/types.h>`

[lib][uefi] Implement events API in UEFI LK already has events APIs. To support events protocols in UEFI spec, I created a wrapper object for LK events. This wrapper object keeps additional data that are necessary to support UEFI events spec: * Notification function, or callbacks * Argument for the notification function * Type of this UEFI event (which specifies when the callback should be called) The events API is essential for supporting async I/O in UEFI. Intended use case looks like: * UEFI app creates an event object, attatch callback to this event * UEFI app calls LK for asynchronous read/write on a block device, with the newly created events object * LK executes IO operation in background, after IO finishes, signal the specified event object * UEFI's callback gets executed 2025-07-14 12:19:51 -07:00			`EfiStatus list_block_devices(size_t num_handles, EfiHandle *buf);`
