Add option to toggle throttled on widgets with interact and depends

[hoxbro]

Is your feature request related to a problem? Please describe.

I often want to use the value_throttled for my dashboard´s widgets and the only way to do it right now is the hard way by adding an explicit widget instance to pn.interact or pn.depends.

Describe the solution you'd like

Either add a keyword like throttled to pn.interact and pn.depends or create a new function which use the value_throttled if it exist for the widget e.g. pn.interact_throttled.

Additional context

Here are examples of pn.interact and pn.depends with a throttled keyword:

I have got an working example of the feature request mentioned above by adding the keyword throttled to the functions pn.interact and pn.depends. I have changed the files panel/interact.py and panel/depends.py to get this to work. I also needed to change panel/widgets/sliders.py so it solves the issues mentioned in #1253 and #1256. I have attached the files changed. Code used above:

import panel as pn
pn.extension()

func = lambda x: x
pn.interact(func, x=1, throttled=True)

import panel as pn
pn.extension()

int_range_slider = pn.widgets.IntRangeSlider(end=10, value=(2, 10), value_throttled=(7, 9))

@pn.depends(int_range_slider, throttled=True)
def print_slider_value(slider_value):
    return slider_value

pn.Column(int_range_slider, print_slider_value)
