Don't set a default size for FT2Font - #30319

Conversation
In the interest of handling non-scalable fonts and reducing font initialization, drop the default size from the `FT2Font` constructor. Non-scalable fonts are sometimes used for bitmap-backed emoji fonts. When we start supporting collection fonts (`.ttc`), then setting a size is a waste, as we will just need to read the count of fonts within. The renderer method `Renderer.draw_text` always sets a size immediately after creating the font object, so this doesn't affect anything in most cases. Only the direct `FT2Font` tests need changes.

Renderer.draw_textalways sets a size immediately after creating the font object, so this doesn't affect anything in most cases. Only the directFT2Fonttests need changes.I'm only unsure whether we wish to somehow warn/deprecate when this the size isn't set explicitly.
