Description

Provide a clear, concise summary of the changes in this PR. What problem does it solve? Why is it needed? Link any related issues using issue closing keywords.

This PR makes it easier to expand or contract one or more selected columns in the query results grid with two simple shortcuts: CTRL + Scroll up (to expand a column/columns) and CTRL + Scroll Down (to contract a column/columns). Full column selection is not required, a single selection in a column and anything in between will work. This also makes expanding a column that trails off the end of the query results WebView much easier to expand.

P.S. my other PR needs review

@croblesm, @caohai - can you take a look at this PR? It seems like a reasonable shortcut to quickly resize columns - not sure if it conflicts with other aspects of the design.

@aasimkhan30 Can you also take a look and see if this aligns with your planned improvements in the query result area?

A few thoughts:

1. VS Code itself has a setting that allows mouse wheel zoom, this feature would conflict with that if editor.mouseWheelZoom is enabled.
   
2. For users with a trackpad (mostly laptop users), wheel event will also capture trackpad "scroll" causing confusion. See this comment from VS Code repo "editor.mouseWheelZoom": true - should be on by default vscode#97137 (comment)

@croblesm Do we want to allow a customizable key binding for column resizing?
