- gltfio: Enable -Wall -Werror for gltfio_core

std::atomic<uint64_t> for older clang
When we call TextureProvider::cancelDecoding, we should make sure
that textures that have been decoded, but not yet used (popped)
should be released (i.e. memory freed and the meta data marked
appropriately.)
Filament does not yet fully support threads with WASM, but this is a
baby step in that direction.
To enable experimental pthreads support, enable the WEBGL_PTHREADS CMake
option. This will enable pthreads support in `gltfio` and `utils`, which
is known to work, but not when served with GitHub Pages.
The web server must emit COOP, COEP and CORP headers, so our build
instructions now recommend the use of `emrun` for local testing.
This also changes our demos so that they do not use unpkg, which
does not work when using `emrun`, due to cross-origin restrictions.
This adds a new implementation of the TextureProvider interface called
Ktx2Provider.
Tested using the KTX2 variant of the StainedGlassLamp model in the
Khronos samples repo.
Tested on WebGL 2.0 (Chrome v100), Android (Pixel 6 Pro), and Desktop
(Metal, OpenGL, and Vulkan via MoltenVK).
This allows clients to provide their own asynchronous texture decoders
for various mime-typed images. This is a plug-in component for gltfio,
in some ways similar to MaterialProvider.
There are two motivations for this: to decouple gltfio from STB and
to make it easier to integrate support for BasisU textures.
This also has the side effect of simplifying ResourceLoader, since the
texture decoding jobs have been moved out.
As part of this work, I made the "stb" CMake target into a traditional
static library. Previously we had several files called `Image.cpp`
whose sole purpose was to enable STB_IMAGE_IMPLEMENTATION.
