LibGfx: Remove single-code point Font::glyph_or_emoji_width API
...
All callers are now aware of multi-code point emoji (and must remain so
going forward).

unambiguously.

LibGfx: Cache font pixel metrics in ScaledFont
...
Instead of recomputing the pixel metrics over and over, we can just
cache them with the font and avoid a bunch of expensive computation.

LibGfx: Make ScaledFont::glyph_height() return the pixel height
...
This was returning the point height which didn't match BitmapFont and
led to bogus line heights in GUI::TextEditor.

LibGfx: Add ability to request glyphs at subpixel offsets to fonts
...
This adds the option to pass a subpixel offset when fetching a glyph
from a font, this offset is currently snapped to thirds of a pixel
(i.e. 0, 0.33, 0.66). This is then used when rasterizing the glyph,
which is then cached like usual.
Note that when using subpixel offsets you're trading a bit of space
for accuracy. With the current third of a pixel offsets you can end
up with up to 9 bitmaps per glyph.

AK+Everywhere: Rename String to DeprecatedString
...
We have a new, improved string type coming up in AK (OOM aware, no null
state), and while it's going to use UTF-8, the name UTF8String is a
mouthful - so let's free up the String name by renaming the existing
class.
Making the old one have an annoying name will hopefully also help with
quick adoption :^)
