Make setFontVariationSettings work with weight adjustment

If setFontVariationSettings is called, the font weight adjustment
no longer adjusted except for the synthetic bolding.

From target SDK 36, because the font variation settings is stored
in the Paint class, it is possible to adjust the weight at runtime
without using synthetic bolding.
