Remove unnecessary WIN32_LEAN_AND_MEAN macro definition

Kernel/SVC: Partially implemented svcReplyAndReceive

gpu: fix edge cases for TextureCopy

gl_rasterizer: use texture buffer for fog LUT

configure_debug: Add label warning that CPU JIT needs to be disabled …

fixing a couple of typos

Services/UDS: Stub SendTo to generate the unencrypted data frames with the right headers

The responsibility of encryption and encapsulation into an 802.11 MAC frame will fall into the callers of GenerateDataPayload.

Kernel/Sessions: Clean up the list of pending request threads of a session when the client endpoint is closed.

It behaves mostly as WaitSynchronizationN with wait_all = false, except for IPC buffer translation.

The target thread of an IPC response will now wake up when responding.
IPC buffer translation is currently not implemented.
Error passing back to svcSendSyncRequest is currently not implemented.

Set definition WIN32_LEAN_AND_MEAN to avoid windows.h including a lot of libs that are usually not used.

Implement CreateSessionToPort and AcceptSession; fix CreatePort

The return parameters were flipped.

Kernel: Implement CreateSession SVC

Change default UI background from white to black.

Kernel/IPC: Support translation of null handles

this is a rebasing error from #2792. It doesn't affect much though, because the later more Apply() call fixes/hides it

gl_rasterizer: fix lighting LUT interpolation

Missed this in my first implementation. Thanks to @wwylele for pointing
out that this was missing.
