wasm: use wasm allocator, rather than page allocator
...
Uses 4x less pages because we're not allocating 1 page (more or less)
per allocation and instead actually bin-packing it a bit.

wasm: use shared, imported memory
...
This switches our wasm build to use "shared" memory. Shared memory can
be shared across multiple web workers, which is something we'll want to
support for our multi-threaded behaviors later.
Shared memory has a number of different restrictions so this updates
zig-js to support it as well as updates some of our functions that need
to be aware of it.

zero-width chars are ignored if they're at col 0
...
This can cause a crash, and is impossible since zero-width chars are
always attached to a prior character. Word-wrapping doesn't come into
play here because this check happens prior to the wrapping.

font: web canvas face has to render to check presentation for cp
...
Since we have no way to detect our presentation (text/emoji), we need to
actually render the glyph that is being requested to double-check that
the glyph matches our supported presentation.
We do this because the browser will render fallback fonts for a glyph if
it can't find one in the named font.
