Support InlineCompletions And NES

Environment (please complete the following information):

Extension (VsCodeVim) version: 1.29.0
VSCode version: 1.99.3
OS: Mac OS 15.5

Problem statement

InlineCompletion and NES are not well supported in vim mode. when users want to add a new line/ or copy paste content the base interactions don't work.

Neither 'o' nor 'p' would trigger InlineCompletion/NES causing our users to miss out on the suggestions

Proposed solution

Add command invocation on the insert/replace actions to call at least the editor.action.inlineSuggest.trigger. Alternatively a new command could be added to inlineCompletion commands and this could be called to avoid "Explicit trigger" sideeffects.

Appendix

Note that this is a long standing problem and is growing more problematic with the increased scope of copilot.

Start by tracing the insert and replace actions in the TypeScript extension and how they invoke VS Code commands. Review the referenced issues and the inline completion command proposal, then verify that the relevant actions trigger inline suggestions or NES behavior without disrupting Vim mode.
