Remove all lcd_filter code.

We reverted the public API for setting lcd_filter font options
back in 1b42bc8033bc , but we had left the implementation which
would examine fontconfig and Xft properties for the option, and
which would call into freetype for subpixel glyph rasterization.

However, I recently realized, (and the test suite had been trying
to tell me for a while), that this approach would cause a
regression for users who were previously using sub-pixel text,
but without sub-pixel rendering built directly into freetype.
That's not acceptable, so all the code is coming out for now.
