Wasm: qmake.bat and qtpath.bat wrapper scripts call non-existent host tools

I build Qt dev/6.5 for Webassembly on Windows and expect the .bat wrapper scrips for qmake and qtpaths to point to the equivalent tools in the "host Qt" installation.

The host tools would be qmake.exe and qtpaths.exe. The wrapper scripts do however try to call the non-existing qmake6.exe and qtpaths6.exe.

@echo off
C:/Users/alportal/dev/qt6_desktop/qtbase/bin\qmake6.exe -qtconf "%~dp0\target_qt.conf" %*

@echo off
C:/Users/alportal/dev/qt6_desktop/qtbase/bin\qtpaths6.exe -qtconf "%~dp0\target_qt.conf" %*

Besides this issue, it would be nice to have paths with consistent directory separator. Either '/' or '\'
