MeasureString was slow mostly because of wrapping: DrawStringRect and
MeasureStringRect re-ran the word wrapper every frame, and it measures
every prefix of every word. Wrapped strings are now cached. The caches
are unordered_maps with an xxhash of the key, and lookups reuse a key
buffer so a hit doesn't allocate. UIContext also skips switching fonts
when measuring in the current style. In a Mac debug build, 200 cached
measures go from 0.26 to 0.06 ms and 10 wrapped paragraphs from 2.1 to
0.01 ms per frame.

Our Qt backend has long been left behind and doesn't even support Vulkan
currently. There would be a lot of work to make it viable, and I don't
think anyone is really interested.
ImGui on SDL will soon fulfill the need for a more classic user interface
with a menu bar on Linux, and on Mac we already have a native UI.
The D2D-based text renderer requires a D3D11 context, which confuses
RenderDoc (it doesn't permit multiple 3D APIs in the same process).
So, let's restore the old GDI renderer and use it if RenderDoc is attached.

* Rename LogType to Log
* Explicitly use the Log:: enum when logging. Allows for autocomplete when editing.
* Mac/ARM64 buildfix
* Do the same with the hle result log macros
* Rename the log names to mixed case while at it.
* iOS buildfix
* Qt buildfix attempt, ARM32 buildfix
* Wrap the display globals in a struct
Makes it easier to search/replace these, for future refactorings.
* Some renaming
* Qt buildfix, also fix the Qt build on Mac (got broken with battery changes)
* Attempt at buildfixing ios
* UWP buildfix
