Description of the new feature/enhancement

Many users, especially those with Emacs muscle memory, expect Ctrl+e to move the cursor to the end of the line (the EndOfLine function).

With the introduction of predictions, many of these same users want to bind Ctrl+e to also accept the full inline suggestion, similar to how RightArrow works.

The current, discoverable way to do this is:

Set-PSReadLineKeyHandler -Chord 'Ctrl+e' -Function AcceptSuggestion

However, this binding completely overrides the original EndOfLine behavior. This forces the user to choose between one function or the other, which is a poor experience.

Proposed technical implementation details (optional)

I propose adding a new, built-in PSReadLine function (e.g., EndOfLineOrAcceptSuggestion) that intelligently combines both behaviors.

The logic for this new function would be:

1. If the cursor is not at the end of the line, perform the EndOfLine action.
2. If the cursor is already at the end of the line, perform the AcceptSuggestion action.

This would create a "smart" key binding that "does the right thing" based on context.
