Improve source selection UX

[hannahblair]

Description

This PR

• Fixes the source selection being cut off in Webcam (and changes it to use the select and option elements so a little a11y win)
• Changes gr.Image to use the source selection component used in Audio and Video for alignment (extra benefit is seeing the selected source icon styling)
  • I've changed active_source logic slightly: 1) it can be any of the sources, not just webcam or null. 2) active_tool renamed to active_source for a tiny bit of consistency cc @pngwn
• Adds a paste from clipboard view when active_source is clipboard
• Improve Video source selection styling (use webcam icon) and UX (couldn't switch to upload from webcam)

Test Demo

import gradio as gr

with gr.Blocks() as demo:
    with gr.Row():
        gr.Image(label="Input", sources=["upload", "webcam", "clipboard"])
        gr.Image(label="Input", sources=["webcam", "webcam"])
        gr.Video(sources=["webcam", "upload"])

demo.launch()

Ah, no (just managed to repro after updating main). But it makes sense to fix it in this PR!

Thanks @hannahblair! I'll mark it as a regression then
