When running selectors for JS linting plugins we would error when
encountering an unknown attribute name:
```js
// selector
Foo[non-existant]
// error
Error: Missing string id: <number>
```
This was caused by using `0` as the invalid marker, but also overloading
`0` with an actual node type. So the fix is to reserve `0` as the
invalid marker and move the property type to the next index.
This PR extracts the core part of
https://github.com/denoland/deno/pull/27203 to make it easier to review
and land in parts.
It contains:
- The JS plugin code the deserializes and walks the buffer
- The Rust portion to serialize SWC to the buffer format (a bunch of
nodes are still todos, but imo these can land anytime later)
- Basic lint plugin types, without the AST node types to make this PR
easier to review
- Added more code comments to explain the format etc.
More fixes and changes will be done in follow-up PRs.
