add fill selection text for quick search

This is a simple version, there are still many problems to solve, i.e. if we select a word in the editor, but we switch the cursor to the left search window, and let the cursor in the input box, the shortcut search will still fill the editor selected word, I think it should not be filled at this time, so I will add judgment for editor is focus

These are all help to correct my code progress ~

Apologies for not commenting on this earlier - I just noticed this while testing your PR.

@TylerLeonhardt This PR looks fine to me, but I did notice that this doesn't work if preserveInput is true. This is because preserveInput takes precedence over any default string (even if defaultFilterValue is defined).

vscode/src/vs/platform/quickinput/browser/quickAccess.ts

Lines 83 to 87 in 26f41a4

	if (defaultFilterValue === DefaultQuickAccessFilterValue.LAST) {
	newValue = this.lastAcceptedPickerValues.get(descriptor);
	} else if (typeof defaultFilterValue === 'string') {
	newValue = `${descriptor.prefix}${defaultFilterValue}`;
	}

Should we edit this somehow, or is this intentional?

@andreamah that seems backwards to me. Can you get an issue going and I'll take a look deeper?

Excited to see this land! Thanks, @weartist!
