Fix EditorInspector tooltip disappearing in special cases

EditorInspector tooltips seems to be affected by waccom drivers after #95044
This makes ProjectSettings, EditorSettings and Inspector tooltips disappear very fast even if you don't move the mouse.
Having a waccom driver installed seems to be enough for this to happen, as I have this issue without a pen tablet connected.

Disabling the internal process of the tooltip's EditorHelpBitTooltip solves this issue.
Everything is still working fine on windows. But some testing in other OS's would be appreciated.

So, I've take a better look on the problem. For some reason on windows, when using the "wintab" driver, the update mouse velocity is a bit delayed. So when the tooltip is created, it triggers,
Because the mouse speed just before you put the mouse inside the tooltip is still there.

if (!_is_mouse_inside_tooltip && OS::get_singleton()->get_ticks_msec() - _enter_tree_time > 250) {
    _start_timer();
}

Increasing this time a little bit seems to solve the issue.

My guess is that the tooltip delay to start the tooltip in inspectors is about 200~250 ms, and a few ms delay that wintab creates is just enough for it to trigger this.

Also a note: the docs and other tooltips are handled very differently, they don't have this 'fix' and work in any case no matter the delay. The tooltip delay ProjectSettings only affect them. And InspectorEditor tooltips are always about a 250ms delay to popup.

But this I feel is another issue that should be handled separately.
For now, adjusting this delay fixes the driver tooltip disappearing issue.
