**Summary**
<!-- Explain the **motivation** for making this change. What existing
problem does the pull request solve? -->
<!-- Try to link to an open issue for more information. -->
Currently methods that return an element handle, i.e. `.$`,
`.waitForSelector` attempt to infer the node element type from the
selector string. However, this only works when the selector is an exact
match of the element tag, i.e. a selector `"a"` would be inferred as
`HTMLAnchorElement` . And not when the selector is complex, i.e.
selectors `"a#some-id"`, `div > a`, `a:nth-child(2)` would all fallback
on `Element`.
This is due to simply looking up the the selector in
`HTMLElementTagNameMap` and `SVGElementTagNameMap` without any attempt
to parse the selector string.
This PR is an attempt to do so.
**Does this PR introduce a breaking change?**
<!-- If this PR introduces a breaking change, please describe the impact
and a migration path for existing applications. -->

This PR moves the puppeteer source code into separate mono-repo packages:
- `puppeteer` and `puppeteer-core` are now separated into their own
packages.
- `puppeteer-core` has a new exports called `puppeteer-core/internal`
for internal usage.
Tests and various tools have been updated to accommodate the migration.
