NativeShutdownGraphics, which Android runs whenever the app loses its
surface, destroyed the imgui context and the ImDebugger along with the
device objects, so window layout and debugger state reset on return.
Now only the device objects go there (the backend already recreates
them), and the context and debugger are torn down in NativeShutdown.
Both configs are still saved on device loss, in case the app is killed
in the background.
imgui.ini is now read and written through our File API rather than
imgui's fopen, which can't reach a memstick behind a content URI.

- Fixes#17608
Text fields took Ctrl or Cmd for copy/paste/undo; now it's Cmd on Apple
platforms and Ctrl elsewhere, as is Ctrl+F (Cmd+F) for game search. Word
delete in the search filter is Option+Backspace on Apple.
The ImGui debugger never got Super, so with ImGui's Mac Cmd/Ctrl swap,
its paste and other Ctrl shortcuts could not be reached at all on Mac.

imgui 1.92 hands the backend a list of dirty rectangles when its font atlas
grows, but thin3d could only replace a whole mip level, so every new glyph
re-uploaded the entire atlas.
Adds DrawContext::UpdateTextureRegions, taking a batch of regions so each
backend can submit them together:
- Vulkan: packs the regions into the push pool and issues a single
vkCmdCopyBufferToImage from the init command buffer, transitioning only
the level being written.
- OpenGL: new TEXTURE_SUBIMAGE init step. The existing sub-image path is a
render command needing an active render pass and a texture slot, which
doesn't fit here. Rows are packed caller-side since GLES2 lacks
GL_UNPACK_ROW_LENGTH.
- D3D11: UpdateSubresource with a box, no staging texture needed.

From 947aa9c97 to 98a66d8c8 on the docking branch - the latest release there,
plus the viewport fixes that landed on top of it. The only local changes to
upstream files are the "#undef new" hack at the top of imgui.h and enabling
IMGUI_DISABLE_OBSOLETE_FUNCTIONS in imconfig.h; both re-applied.
1.92 reworked fonts and textures, so the thin3d backend now advertises
ImGuiBackendFlags_RendererHasTextures and creates/updates/destroys imgui's
textures on request instead of building the font atlas itself. ImTextureIDs
below 256 now index those, above it the per-frame temp textures as before.
thin3d can't replace part of a texture yet, so an update re-uploads the whole
thing - fine for an atlas that only changes when a new glyph appears.
Also: AddRect() swapped its thickness and flags parameters in 1.92.8.
