Workbench hover to align and correctly apply delay setting

[benibenj]

This PR refactors the usage of the hover service across various components. Instead of directly using the hover service, a new WorkbenchHoverDelegate is created and used. This delegate encapsulates the hover service and provides a consistent interface for components to use. This change simplifies the code and makes it easier to manage hover behavior across the workbench. Compared to the previous implementation, the delay will adapt when the configuration is changed without having to reload.

Thanks for driving this.

I think there are a lot more places where the custom hover is installed where maybe we could think about more reuse. To give some examples:

vscode/src/vs/workbench/browser/parts/statusbar/statusbarPart.ts

Lines 147 to 153 in ec85082

	get delay() {
	if (Date.now() - this.lastHoverHideTime < 200) {
	return 0; // show instantly when a hover was recently shown
	}
	return this.configurationService.getValue<number>('workbench.hover.delay');
	}

vscode/src/vs/base/browser/ui/iconLabel/iconLabelHover.ts

Line 165 in ec85082

export function setupCustomHover(hoverDelegate: IHoverDelegate, htmlElement: HTMLElement, content: IHoverContent, options?: IUpdatableHoverOptions): ICustomHover {

Adopted it in further cases. I extended it to also be able to enable if the hover should instantly be shown after hovering over another element. Also the consumer can now add options to override the defaults.
There are still more cases that could be considered, but I think this is a good start as the others are a bit more complicated. Planning on extending the custom hover across further areas in debt week

I have feedback, but will file a new issue.
