**Motivation**
Update the vitest to avoid using third party test pool.
**Description**
- Use latest vitest
- Remove custom process pool which we developed to run our tests in Bun
runtime
- Migrate test configs to latest version
- Update types
- Switch to playwright from webdriverio for browser tests performance,
which was due for long.
**Steps to test or reproduce**
- Run all tests
**Motivation**
- #7280
**Description**
- update `@types/node` to the latest node v22 version
- add `@lodestar/bun` dependency using git+https (for now! so that we
don't have to republish a bazillion times)
- keep in mind that this requires a manual build/rebuild of the so (via
`cd node_modules/@lodestar/bun && zig build`)
- Add a bun-specific `LevelDbController` which uses
[`@lodestar/bun`](https://github.com/ChainSafe/lodestar-bun)
- Only expose the leveldb controller via a subpath export (and for
tests, as a custom import, like in #8320 )
- add bun bun global override types
**Motivation**
Use latest `module` and `moduleResolution` for TS.
**Description**
- To use [subpath
imports](https://nodejs.org/api/packages.html#subpath-imports) in the PR
#8320 we need to update the module solution strategy for TS.
- That requires to change the `module` for the TS as well.
- Earlier tried to stay with `node18` or `node20`, but the `ts-node`
does not work with that.
- Maintaining different tsconfig for ts-node is more of hassle on wrong
run.
- So decided to stick with `nodenext` strategy for `moduleResolution`
**Steps to test or reproduce**
