This PR provides WASM extensions with write access to their own specific working directory under the Zed `extensions` dir. This directory is set as the extensions `current_dir` when they run. Extensions can return relative paths from the `Extension::language_server_command` method, and those relative paths will be interpreted relative to this working dir. With this functionality, most language servers that we currently build into zed can be installed using extensions. Release Notes: - N/A
