de4f256d48 Wasm: enable thread support
configure.json: Make the “thread” feature be allowed
for wasm but disabled by default.

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

79e4fe54bf WebAssembly: Fix compilation of application on Windows host
When running configure on a Windows host, it would fail with the
error that the copy statement was invalid, due to the forward
slashes. This makes configure finish without errors.

54dabdd1e8 wasm: fix qpa plugin build system integration
fix the plugin name (it was missing the leading 'q') and the name used
in configure (the latter making it unnecessary to mess with it in the
mkspec). the qt.prf override which forced linkage of the plugin is also
removed due to being completely redundant.
