Measure individual words instead of just line breaks for text exports (#1397)
This diff fixes a number of issues with text export by completely
overhauling how we approach laying out text in exports.

Currently, we try to carefully replicate in-browser behaviour around
line breaks and whitespace collapsing. We do this using an iterative
algorithm that forces the browser to perform a layout for each word, and
attempting to re-implement how the browser does things like whitespace
collapsing & finding line break opportunities. Lots of export issues
come from the fact that this is almost impossible to do well (short of
sending a complete text layout algorithm & full unicode lookup tables).

Luckily, the browser already has a complete text layout algorithm and
full unicode lookup tables! In the new approach, we ask the browser to
lay the text out once. Then, we use the
[`Range`](https://developer.mozilla.org/en-US/docs/Web/API/Range) API to
loop over every character in the rendered text and measure its position.
These character positions are then grouped into "spans". A span is a
contiguous range of either whitespace or non-whitespace characters,
uninterrupted by any browser-inserting line breaks. When we come to
render the SVG, each span gets its own `<tspan>` element, absolutely
positioned according to where it ended up in the user's browser.

This fixes a bunch of issues:

**Misaligned text due to whitespace collapsing at line breaks**

**Hyphenated text (or text with non-trivial/whitespace-based breaking
rules like Thai) not splitting correctly**

**Frame labels not respecting multiple spaces & not truncating
correctly**

#### Quick note on browser compatibility
This approach works well across all browsers, but in some cases actually
_increases_ x-browser variance. Consider these screenshots of the same
element (original above, export below):

![image](https://github.com/tldraw/tldraw/assets/1489520/5633b041-8cb3-4c92-bef6-4f3c202305de)

Notice how on chrome, the whitespace at the end of each line of
right-aligned text is preserved. On safari, it's collapsed. The safari
option looks better - so our manual line-breaking/white-space-collapsing
algorithm preferred safari's approach. That meant that in-app, this
shape looks very slightly different from browser to browser. But out of
the app, the exports would have been the same (although also note that
hyphenation is broken). Now, because these shapes look different across
browsers, the exports now look different across browsers too. We're
relying on the host-browsers text layout algorithm, which means we'll
faithfully reproduce any quirks/inconsistencies of that algorithm. I
think this is an acceptable tradeoff.

### Change Type

- [x] `patch` — Bug Fix

### Test Plan

* Comprehensive testing of text in exports, paying close attention to
details around white-space, line-breaking and alignment
* Consider setting `tldrawDebugSvg = true`
* Check text shapes, geo shapes with labels, arrow shapes with labels,
note shapes, frame labels
* Check different alignments and fonts (including vertical alignment)
