Suppress ES-compiler warnings against the ES-262 test-suite

V4's ES-compiler warns about assorted variables in the ES-262
test-suite being used before declaration. We aren't about to fix that
test-suite, so the warnings are just noise to us. As there are many of
them, they overflow the QTestLib logger's -maxwarnings threshold,
causing actually relevant messages (like test failures) to be lost in
the output.

Install a trivial QLoggingCategory::CategoryFilter to filter out
warnings and debug for the qt.qml.compiler category (and all
sub-categories of it). Condition this on a define so that someone who
actually wants to see those warnings can turn them on.

Pick-to: 6.4
