imgui: reorganize imgui library files to mirror what's in the imgui releases (#285)

## Link to GitHub Issue, if one exists

## Description of change
Functionally, no change.

Move ImGui library files around so that they mirror how they are
structured in imgui releases. This will make it easier to migrate to a
future version of ImGui.

Add a handful of static asserts to check that we have the necessary
features enabled / disabled in imgui header.

## Compiling
👍 

## Testing
Tested 32-bit overlay, 64-bit overlay, TDJ, and UFC overlays, and
spicecfg.

Interesting finds during ImGui testing (not part of this PR, but for
future reference when upgrading imgui version):
* Updating dx9 backend to the newest causes TDJ to stop rendering the
overlay completely (fine in UFC or any other game)
* Omitting `IMGUI_USE_BGRA_PACKED_COLOR` causes spicecfg software
renderer to use the wrong color (RGB format parsing error probably)
* At some point - v1.90? the `About` and `Licenses` buttons in spicecfg
stop responding after an upgrade, maybe our improper usage of MenuItem?
* Using the docking branch of ImGui is not required but we should just
stick to it for multi-viewport functionality which we may want to use
later.

// dear imgui: wrappers for C++ standard library (STL) types (std::string, etc.)
// This is also an example of how you may wrap your own similar types.
// Changelog:
// - v0.10: Initial version. Added InputText() / InputTextMultiline() calls with std::string
// See more C++ related extension (fmt, RAII, syntaxis sugar) on Wiki:
