Summary:
Make delimiter sizing work. This involved
- Adding the symbols for the remaining delimiters (like `\lfloor` and `\{`)
- Adding metrics for the size1, size2, size3, and size4 fonts
- Parsing delimiter sizing functions
- Using the big fonts when possible, otherwise building large copies of the
delimiters from scratch
Test Plan:
- See that
`\bigl\uparrow\Bigl\downarrow\biggl\updownarrow\Biggl\Uparrow
\Biggr\Downarrow\biggr\Updownarrow\bigm/\Bigm\backslash\biggm|
\Biggm|\big\lceil\Big\rceil\bigg\langle\Bigg\rangle\bigl(\Bigl)
\biggl[\Biggl]\Biggr\{\biggr\}\Bigr\lfloor\bigr\rfloor`
parses correctly (this contains all of the delimiters, and all of the sizing
modes)
- See that the huxley tests didn't change, and the new one looks good
- See the normal tests work

Summary:
\nleq and \ngeq are AMS characters, so add support for parsing and
showing those. Also, add font metrics from the ams_regular font.
Test Plan:
View `\ngeq \geq`, make sure that they look the same but with a
slash through `\ngeq`. View `a \ngeq b`, make sure there's the right spacing
for a rel.

Summary:
Fixes T1325.
This has the advantage of not having to do the mapping manually. Also it means that characters like \neq are included in the mapping, so this resolves T1323 as well.
I opted to group the metrics by character instead of by metric type because I think it'll gzip better and it makes getCharacterMetrics simpler anyway.
Test Plan: The test page looks identical to the pixel to my eye.
