Inline Autocompletion Pt.2 (#333)

* Add first draft of inline code completion with mock text

* Adds InsertInlineTextAction for inserting autocomplete suggestion with tab

- Changed to disable suggestions when text is selected
- Adds and removes the insert action based on when it shows the inlay hint

* Request inline code completion

* Move inline completion prompt into txt file

* Add inline completion settings to ConfigurationState

* Fix code style

* Use EditorTrackerListener instead of EditorFactoryListener to enable inline completion

* Code completion requests synchronously without SSE

* Use LlamaClient.getInfill() for inline code completion

* support inlay block element rendering, clean up code

* Use only enclosed Method or Class contents for code completion if possible

* Refactor extracting PsiElement contents in code completion

* bump llm-client

* fix completion call from triggering on EDT, force method params to be nonnull by default

* refactor request building, decrease delay value

* Trigger code completion if cursor is not inside a word

* Improve inlay rendering

* Support cancellable infill requests

* add statusbar widget, disable completions by default

* Show error notification if code completion failed

* Truely disable/enable EditorInlayHandler when completion is turned off/on

* Add CodeCompletionEnabledListener Topic to control enabling/disabling code-completion

* Add progress indicator for code-completion with option to cancel

* Add CodeCompletionServiceTest + refactor inlay ElementRenderers

* several improvements

- replace timer implementation with call debouncing
- use OpenAI /v1/completions API for completions
- code refactoring

* trigger progress indicator only for llama completions

* fix tests
