cc: Toggle LCD text at raster time instead of record time.

Always tell blink that it can use LCD text (in future this can stop
being passed at all). And at raster time:

- If LCD text is allowed initialize SkSurfaceProps with the LegacyHost
parameter which will cause skia to pick an LCD text format matching
current behaviour.
- If LCD is not allowed initialize SkSurfaceProps with an "unknown
pixelformat" causing LCD text to not be used.

This also removes the need for SK_SUPPORT_LEGACY_TEXTRENDERMODE from
resource_provider.cc.
