Switched from sub-pixel to greyscale text anti-aliasing on macOS when running with a JetBrains JRE.

Browse Source 
Sub-pixel anti-aliasing (VALUE_TEXT_ANTIALIAS_LCD_HRGB) causes font rendering with too much weight with a JetBrains JREs (both 8 and 11). This can be seen when comparing the text rendering of UI elements between IntelliJ IDEA and FlatLaf.

This commits aligns FlatLaf's behavior with IntelliJ IDEA which disables sub-pixel anti-aliasing on macOS for its IDE anti-aliasing setting and uses greyscale anti-aliasing by default (see com.intellij.ide.ui.AntialiasingType.canUseSubpixelAAForIDE).
