IPC: skip empty buffer write

prevent yuzu crash, if games, like Axiom Verge, trying to read 0 bytes from file

Service/Audio: update audren:u service

* Start to add NCA support in loader

* More nca stuff

* More changes to nca.cpp

* Now identifies decrypted NCA cont.

* Game list fixes and more structs and stuff

* More updates to Nca class

* Now reads ExeFs (i think)

* ACTUALLY LOADS EXEFS!

* RomFS loads and games execute

* Cleanup and Finalize

* plumbing, cleanup and testing

* fix some things that i didnt think of before

GPU: Perform negation after absolute value in the float shader instructions.

Avoid initializing single-joycon layouts with handheld controller

GPU: Don't mark uniform buffers and registers as used for instructions which don't have them.

Like the MOV32I and FMUL32I instructions.
This fixes a potential crash when using these instructions.

gl_rasterizer: Implement texture format ASTC_2D_4X4.

Add UI support for extracted NCA folders

svc: Add a stub for UserExceptionContextAddr.

gl_rasterizer: Get loose on independent blending.

gl_rasterizer_cache: Loosen things up a bit.

gl_shader_decompiler: Implement LOP instructions.

gl_shader_decompiler: Implement register size conversions for I2I and I2F.

gl_shader_decompiler: Implement LOP32I LogicOperation PassB.

gl_shader_gen: Set position.w to 1.

Qt: Removed the Registers widget.

It was crashing and nobody actually uses this.
