Morten Sørvig be44827240 wasm: add support for building Qt as shared libraries 
This implements the build system bits required to build Qt
as as separate wasm modules a.k.a Emscripten side modules.

Enable by configuring with the "-shared" flag.

This is the first step towards shared library support and gets
us as far as being able to load QtCore and instantiate a
QCoreApplication.

Task-number: QTBUG-63925

# Work around global target promotion failure when WrapZLIB is used on APPLE platforms.
# What ends up happening is that the ZLIB::ZLIB target is not promoted to global by qt_find_package,
# then qt_find_package(WrapSystemPNG) tries to find its dependency ZLIB::ZLIB, sees it's not global
# and tries to promote it to global, but fails because the directory scope of the PNG package is
# different (src/gui) from where ZLIB was originally found (qtbase root).
# To avoid that, just manually promote the target to global here.
