 hle_ipc: Make GetDomainMessageHeader return a regular pointer

Gets rid of the need to call the getter and then check for null.

Nothing requires the shared owner ship here, so we can just return a
plain pointer.

core: Add missing const variants of getters for the System class

Implemented Mipmaps

time_stretch: Switch to values of Citra

video_core: Move OpenGL specific utils to its renderer

renderer_opengl: Enable alpha channel for DXT1 texture format

renderer_opengl: Correct bpp value for ASTC_2D_8X5_SRGB

Many of the Current<Thing> getters (as well as a few others) were
missing const qualified variants, which makes it a pain to retrieve
certain things from const qualified references to System.

renderer_opengl: Correct bpp value for ASTC_2D_8X5

Improved Shader accuracy on Vertex and Geometry Shaders.
