Uses ScratchBuffer and avoids overwriting the command_headers buffer with the prefetch_command_list

This class creates a default initialized heap allocated buffer for cases where value initializing members during allocation or resize
is redundant.

kernel: add KHardwareTimer

input_common: Cleanup project

overlay_dialog: Hide button dialog box when both buttons are hidden

This allows for the creation of a non-interactive dialog overlay to display system messages.

service: nfc: Silence ListDevices

Use execlp instead of execl to avoid failure

input_common: Add virtual gamepad

Vulkan: Add support for VK_EXT_depth_clip_control.

qt: avoid setting WA_DontCreateNativeAncestors on all platforms

qt: handle wayland-egl platform name

camera: Use pre-allocated vector for camera data

hle_ipc: Refactor ReadBuffer to set buffer size upon initialization

[audio_core] Signal buffer event on audio in/out system stop

Remove unimplemented geometry transform feedback log spam

And avoid an unnecessary copy

Set: Allow setting device nickname

hle_ipc: Reserve vectors before populating

kernel: process: Implement GetFreeThreadCount
