chore: explore parsers and printers

[manuel3108]

Closes #44
Relates #100

This basically duplicates #100 at this point. See #100 for up and downsides of this approach.

I was initially intending to get rid of a lot more dependencies (like the dependencies for handling html) and use svelte-ast-print instead, but this was opening too many issues at the same time. That's why I opted to "only" switch to acorn and esrap here, the rest can be done later.

Relevant PR's

• feat: support indexed access type esrap#18
• feat: add option for quote and indentation styles esrap#19

Benefits

• closer to other tools in the svelte ecosystem
• Faster bundling (~33% speed improvement locally from 4s to 3s, probably more with chore: use rolldown #371)
• Smaller bundle (locally 2.6MB vs 3.6MB)
• more consistent formatting than the strange things we sometimes experienced with recast
• we are in full control of the printing, as we can control esrap

Downsides

• More tooling that we need to control (code to maintain)
• Our custom typing for TSEstree as no good public alternative exists, that matches acorns output. We do have @typescript-eslint/types but that was just the one with the smallest pain points. Still exploring other options.
