fix(replay): Add missing rrweb type declarations (#6464)

To generate type declarations, we use `tsc` (`yarn build:types`) which doesn't pull external type declarations into the resulting `.d.ts` files. We import types from rrweb which our internal types rely on. Because we now vendor rrweb, the rrweb-internal types are no longer getting installed in our users node_modules, producing typescript errors when they build their projects. To hotfix this, this PR vendors a "light" version of the two rrweb types we use.
