graphics/glfw: make PREEDIT option default
PREEDIT option adds patches for run Minecraft [1].
Many of the users use this port specifically for Minecraft and they have
to build it manually from the ports. These experimental patches have
been used for playing Minecraft by various players for 3 months now, so
I think it’s acceptable to include them in the default build in the
latest, but not to make MFH yet.
If no regressions are identified in other consumers before the next
quarterly branch (2024Q4) is created, then I will leave it that way.
