Our WebGL 2 support is half finished, since we use surface format verion of 3
to map to webgl2, but do not enable Open GL ES3 needed for WebGL2 support.
This allows glDrawArrays and glDrawElements to be used

If qmake is called without sh.exe in PATH, the relative paths
in OBJECTS will contain backslashes as separator.
Anyhow, emar needs forward slashes. Use GNU make's subst command
to fix this.
This amends 22c1e10e19.

On Windows we hit the command line length limit when building the wasm
port of Qt. We must not pass the list of object files directly to emar,
but write a response file which is then passed via the @ parameter.

Compilation breaks on Windows and macOS hosts with USE_ZLIB=1.
In addition, it turns out that the versions of the libraries in
Emscripten Ports are outdated. Since we have newer versions
of these libraries in Qt already, we will just use those.
This is a revert of 70b558ad5b.

Opt-in by passing “-device-option WASM_OBJECT_FILES=1”

This requires a custom emsdk build which uses upstream

Change qmake.conf and wasm.prf to enable Emscripten
pthreads mode:
- Add USE_PTHREADS=1 linker flag
- Add PTHREAD_POOL_SIZE linker flag with a default pool size (4).
- Add TOTAL_MEMORY linker flag to set available memory (1GB)
It is possible to override options such as PTHREAD_POOL_SIZE
from the application .pro file using QMAKE_WASM_PTHREAD_POOL_SIZE
To change TOTAL_MEMORY, use QMAKE_WASM_TOTAL_MEMORY
Make qtloader.js work in pthreads mode:
- The Module.instantiateWasm callback must provide the module
in addition to the instance to Emscripten.
- Set Module.mainScriptUrlOrBlob so that the pthreads web workers
can access the main script

removed due to being completely redundant.
