fix(Button): redesign of existing Button component

[jbocce]

Context

New Button component designs thanks to @dan-rukas (see the screen shots below). The redesign improves various items:

1. A consistent look-and-feel with the rest of OHIF with better button styles, sizes and colours

2. A reduction in complexity for developers using the Button. The previous Button component allowed for many (too many) variant, colour and border permutations, making for a confusing developer experience. Furthermore, with so many permutations, maintaining a consistent button look-and-feel proved to be very difficult. Now there are four basic permutations:

<Button type={ButtonEnums.type.primary} size={ButtonEnums.size.medium}/>
<Button type={ButtonEnums.type.secondary} size={ButtonEnums.size.medium}/>
<Button type={ButtonEnums.type.primary} size={ButtonEnums.size.small}/>
<Button type={ButtonEnums.type.secondary} size={ButtonEnums.size.small}/>

3. A disabled button is no longer a variant or type, but instead just a boolean attribute of the Button like so...

<Button disabled={true}}/>

Changes & Results

• Copied ui/Button to ui/LegacyButton and replaced Button with LegacyButton in ButtonGroup components.
• Altered the Button component to match the new styles.
• Updated various uses of the Button component.
• Uses of Button component that did NOT match the new design were changed to LegacyButton.
• LegacyButton uses will be changed/addressed in future redesigns.
• Updated the Button Storybook.

Testing

All the various uses of Button should reflect the new design. Those that do NOT include...

• ButtonGroup buttons
  
• various Worklist buttons like those for launching modes and clearing filters

Looks great, see my comments and maybe update the PR before the first image to explain that this is done to reduce the complexity of variants and colors and etc etc, and maybe just mention the 4 different syntaxes they can use now (instead of who knows how many before)
