[issue30521] IDLE: Add navigate bar and replace current goto dialog

[Louie Lu]

New submission from Louie Lu:

Propose a sublime-like navigate bar to replace current goto dialog.

Navigate bar current support two different mode: prefix ':' for goto line, and prefix '@' for goto symbol.

When user use shortcut Ctrl+G to open goto line, it will prompt out a navigate bar on the top of the editor.text with prefix ':', user can enter valid lineno, and it will highlight the line on the editor.

After return, it will close the navigate bar and clear the highlight, user cursor will be set to the target lineno.
