Relands #19463. This time the `ExtensionFileSourceCode` enum is
preserved, so this effectively just splits feature
`include_js_for_snapshotting` into `exclude_js_sources` and
`runtime_js_sources`, adds a `force_include_js_sources` option on
`extension!()`, and unifies `ext::Init_ops_and_esm()` and
`ext::init_ops()` into `ext::init()`.
The Deno Language Server provides a server implementation of the
Language Server Protocol
which is specifically tailored to provide a Deno view of code. It is
integrated into the command line and can be started via the lsp sub-command.
This documentation has been moved to the
Deno manual.
