Backends: moved global to a data structure to facilitate support for multi-contexts. (#586, #1851, #2004, #3012, #3934, #4141)
This is NOT enable multi-contexts for any backends - in order to make this commit as harmless as possible, while containing all the cruft/renaming -

// 2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
|

// 2021-06-25: DirectX9: Explicitly disable texture state stages after >= 1.

// 2021-05-19: DirectX9: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement)

// 2021-04-23: DirectX9: Explicitly setting up more graphics states to increase compatibility with unusual non-default states.
