qmllint: Integrate type inference warnings

This change helps bring in type inference and compiler warnings previously only generated by qmlcachegen+.
These warnings are disabled by default and have to be enabled manually via the --compiler option.

Also makes the logger handle zero length SourceLocations properly by just highlighting the entire line instead of hitting an assert.
