155170262a Backends: DX9, Allegro5, SDLRenderer2, SDLRenderer3: Defer texture destruction until UnusedFrames > 0 (#8597, #9475)
These four backends were missing the UnusedFrames > 0 check in their
UpdateTexture() WantDestroy branch, inconsistent with all other backends
(OpenGL2, OpenGL3, DX10, DX11, DX12, Vulkan, WGPU, SDLGPU3) which already
defer destruction until the texture is no longer in flight.

This is a potential use-after-free in multi-threaded/staged rendering
pipelines where the UI thread may destroy a texture while the render thread
is still drawing with it. Per #8597 guidance: backends should defer
destroying by the amount of in-flight frames in their rendering pipeline.

The fix adds '&& tex->UnusedFrames > 0' to the WantDestroy condition,
matching the exact pattern used by OpenGL3, DX10, DX11, WGPU, and SDLGPU3.

Companion to #9475 (OpenGL2 fix, already merged).

e816bc6723 Merge misc changes from docking branch to reduce small drift.
In particular:
- imgui.cpp : move UpdateInputEvents() higher in NewFrame() to match docking + update RenderMouseCursor() to match.
- imgui_draw.cpp: ImDrawList::_ResetForNewFrame() change from c807192ab
- Backends: SDL2. Add MouseWindowID + change SDL_CaptureMouse() test to match docking branch. Not strictly necessary but aimed at reducing drift because we go on and fork this file.
+ moved responsability of checking valid names to TabBarGetTabName() to simplify both branches.
