refactor(lsp): clean up "enablePaths" handling (#20388)

Previously we pre-computed enabled paths into `Config::enabled_paths`,
and had to keep updating it. Now we determine enabled paths directly
from `Config::settings` on demand as a single source of truth.

Removes `Config::root_uri`. If `InitializeParams::rootUri` is given, and
it doesn't correspond to a folder in
`InitializeParams::workspaceFolders`, prepend it to
`Config::workspace_folders` as a mocked folder.

Includes groundwork for
https://github.com/denoland/vscode_deno/issues/908. In a minor version
cycle or two we can fix that in vscode_deno, and it won't break for Deno
versions post this patch due to the corrected deserialization logic for
`enablePaths`.
