This patch caches VAO objects instead of re-emiting all pointers per draw call.
Configuring this pointers is known as a fast task, but it yields too many GL
calls. So for better performance, just bind the VAO instead of 16 pointers.

renderer_opengl: Implement a buffer cache.

The idea of this cache is to avoid redundant uploads. So we are going
to cache the uploaded buffers within the stream_buffer and just reuse
the old pointers.
The next step is to implement a VBO cache on GPU memory, but for now,
I want to check the overhead of the cache management. Fetching the
buffer over PCI-E should be quite fast.

gl_shader_cache: Use an u32 for the binding point cache.

file_sys: Add Nintendo Submissions Package (NSP) file format

The std::string generation with its malloc and free requirement
was a noticeable overhead. Also switch to an ordered_map to
avoid the std::hash call. As those maps usually have a size of
two elements, the lookup time shall not matter.

Eliminated duplicate code and adds support for Rev1+ carts

Previously only loaded from control metadata

common/logging: Minor changes

Optimizations

file_sys: Allow for custom NAND/SD directories

gl_shader_decompiler: Use used_shaders member variable directly within GenerateDeclarations()

file_sys: Replace includes with forward declarations where applicable

Update microprofile scopes.

ssl: Move SSL class to cpp file

Multi-line doc comments still need the '<' after the ///, otherwise it's
treated as a regular comment and makes the original doc comment broken
in viewers, IDEs, etc. While we're at it, also fix some typos in the
comments.

Implicit conversions aren't desirable here.

This helper is called very often. The memory ownership shall not be transfered, so just return the raw pointer.

subchannel is a 3 bit field. So there must not be more than 8 bound engines.
And using a hashmap for up to 8 values is a bit overpowered.

Blame the subsystems which deserve the blame :)

The updated list is not complete, just the ones I've spotted on random sampling the stack trace.

Cuts down on include dependencies, resulting in less files that need to
be rebuilt when certain things are changed.

service: Migrate global named port map to the KernelCore class

vfs_real: Forward declare IOFile

externals: Update dynarmic to 0435ac2
