This reverts commit 4a152767286717fa69bfc94846a124a366f70065.

Wait for shader to build before configuring it, and wait for the shader
to build before sharing it with other contexts.

This allows us invalidating OpenGL and Vulkan separately in the future.

Adheres to GL_ARB_separate_shader_objects requirements

Ensures that states set for a particular stage are not attached to other
stages which may not need them.

Silences the following warnings-turned-errors:
-Wsign-conversion
-Wunused-private-field
-Wbraced-scalar-init
-Wunused-variable

And some other errors

This change adds two new context menu items to remove either the OpenGL or the Vulkan shader caches individually, and the provides the option to remove all caches for the selected title.
This also changes the behavior of the open shader cache option. Now it creates the shader cache directory for the title if it does not yet exist.

The current implementation is prone to causing graphical issues. Disable until a better solution is implemented.

Fix regression on Fire Emblem: Three Houses when using native fp16.

Workaround potential bug on Nvidia's driver where only updating high
attributes leaves low attributes out dated.

account for the fact that program.*memory_size is in units of bytes.
