- This does not actually seem to exist in the real kernel - games reset these automatically.

core/am: Stub InitializeApplicationCopyrightFrameBuffer, SetApplicationCopyrightImage and SetApplicationCopyrightVisibility

These commands require Screenshots to be implemented anyway, so they are safe to stub for now.

Port citra-emu/citra#4948: "citra_qt: add amiibo drag and drop support"

Co-Authored-By: Valentin Vanelslande <vvanelslandedev@gmail.com>

Global memory is still using the stream buffer when it shouldn't. As a
temporary fix re-enable the stream buffer on compute.

Nvidia's OpenGL driver maps gl(Named)BufferSubData with some requirements
to a fast. This path has an extra memcpy but updates the buffer without
orphaning or waiting for previous calls. It can be seen as a better
model for "push constants" that can upload a whole UBO instead of 256
bytes.

This path has some requirements established here:
http://on-demand.gputechconf.com/gtc/2014/presentations/S4379-opengl-44-scene-rendering-techniques.pdf#page=24

Instead of using the stream buffer, this commits moves constant buffers
uploads to calls of glNamedBufferSubData and from my testing it brings a
performance improvement. This is disabled when the vendor is not Nvidia
since it brings performance regressions.

shader_ir: Fix regression on TLD4

Originally on the last commit I thought TLD4 acted the same as TLD4S and 
didn't have a mask. It actually does have a component mask. This commit 
corrects that.

shader_ir: Fix TLD4 and add bindless variant

This commit fixes an issue where not all 4 results of tld4 were being
written, the color component was defaulted to red, among other things.
It also implements the bindless variant.

kernel/scheduler: Minor changes

gl_state: Miscellaneous clean up

rasterizer_accelerated: Add intermediary for GPU rasterizers

savedata_factory: Automatically create certain savedata
