a30f9ccd33 [GPU] Treat color and alpha sources as two separate RGBA values 
Previously we fetched the RGB channels of the color source and the alpha channel of the alpha source
and combined these into a single RGBA source value that the source operands are applied to.
This is incorrect. The correct behavior is to fetch the full RGBA color for both the color and alpha
sources and to apply the color operand to the color source and the alpha operand to the alpha source,
i.e. using the *alpha* source R-channel when the alpha operand is "One minus source red".
Only after that we combine both sources into a single RGBA color.

62fdb29646 Add GPU_DEBUG_INFO CMake-Option 
Adds a project-wide setting for allowing renderer code to add additional
diagnostic data.  Currently used to allow `opengl.hpp` to conditionally
implement debug-labeling and scopes.

dbf0597bd8 Add DebugScope utility-class for RAII-based OpenGL debug-scopes 
Simply define this object in a C++ scope like:
```cpp
OpenGL::DebugScope glScope("Renderer::display");
```
and it will associate all functions within the current scope within a
named group. Supports `printf` formatting.

1b9f270b19 Migrate IOFile implementation to io_file.cpp 
Makes the implementation of `IOFile` private, allowing inclusions and
defines such as `#define fseeko` and `#include <io.h>` to not poison
client-code or the global namespace.

134e16d8ea Replace Texture::Formats with PICA::ColorFmt

definition.

553d23974a Use std::span to pass vertex data 
Starts utilizing
[std::span](https://en.cppreference.com/w/cpp/container/span) to
indicate a non-owning view of a contiguous array of elements rather than
`T* data, usize count`.

fde93381a5 Use std::span for CPU register-state 
Following the trend of #33: `std::span` provides some useful utility
functions like `size_bytes()` and `as_bytes()` and serves as a better
non-owning "chunk of data"-type over just passing around an
`std::array&`.
