Hide inline overlays when context menu is open (#45266)

Closes #23367 

**Summary**
- Prevents inline diagnostics, code actions, blame annotations, and
hover popovers from overlapping with the right-click context menu by
checking for `mouse_context_menu` presence before rendering these UI
elements.

PS: Same behaviour is present in other editors like VS Code.
