[rcore_desktop_rgfw] [emscripten] fix typo (#5687)

* RGFW also requires RGBA8 images as window icons, as raylib already reports in raylib.h

* LibraryConfigurations.cmake: exchanged MATCHES -> STREQUAL in platform choosing if-statements

* WebRGFW: remapping mouse/touch position to canvas pixel coordinates

* fix 'typo'

* has to be done like that because of += in case of captured mouse

* [rcore_desktop_rgfw] [emscripten] fix typo
