987cca7bca wasm: allow setting total memory for non thread builds
Using WASM_OBJECT_FILES does not allow memory growth, so we need to just
explicitly check for QMAKE_WASM_TOTAL_MEMORY

2a2f04205c WASM: Make wasm_shell.html compatible with CMake configure_file
The CMake configure_file command is commonly used copy & modify template files
during the build process. One limitation, thought, is that configure_file
expect the variables to be replaced to be encoded using either a @APPNAME@ or
${APPNAME} convention.

This commit therefore changes "APPNAME" to "@APPNAME@" in wasm_shell.html to
make the HTML template file compatible with CMake configure_file.

With this commit, it becomes possible to write the following CMake function
that mimics what QMake is already doing:
function(copy_html_js_launch_files target)
  set(APPNAME ${target})
  configure_file("${_qt5Core_install_prefix}/plugins/platforms/wasm_shell.html"
                 "${target}.html")
  configure_file("${_qt5Core_install_prefix}/plugins/platforms/qtloader.js"
                 qtloader.js COPYONLY)
endfunction()

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.
