Support workspace/executeCommand for actions' data (#26239)

Closes https://github.com/zed-industries/zed/issues/16746
Part of https://github.com/zed-extensions/deno/issues/2

Changes the action-related code so, that

* `lsp::Command` as actions are supported, if server replies with them
* actions with commands are filtered out based on servers'
`executeCommandOptions`
(https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#executeCommandOptions)
— commands that are not listed won't be executed and the corresponding
actions will be hidden in Zed

Release Notes:

- Added support of `workspace/executeCommand` for actions' data
