UI: New icon library

[cdedreuille]

What I did

Storybook has a new icon library that is used across our entire set of products available here. In this PR we are replacing the old icon library set in @storybook/components in favour of @storybook/icons.

The transition is made in 2 steps. First in 8.0:

• Remove all svgs from the Icons and Symbols components.
• Deprecate the Icons and Symbols components.
• Add match system to map the list of old props to new components.
• Import @storybook/icons and use it under the hood on the Icons and Symbols components.
• Replace all instances of the old Icons and Symbols components in the monorepo.

In 9.0 we will:

• Remove the Icons component, making use of the full tree-shaking of the new @storybook/icons library.
• Remove the Symbols component

Todo:

• Add mention on the MIGRATION.md file
• Replace all icons
• Tooltip ListItems -> Replace how icons work

There is a 3% increase in static build size from this change (8.615e6 bytes vs 8.378e6). This is small enough that we can probably disregard it and bring the size down in other ways. cc @ndelangen @JReinhold @vanessayuenn
