cleanupEnableBackground should remove inline styles too

[jdufresne]

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

Given the SVG:

<svg height="100" width="100" style="enable-background:new 0 0 100 100"><circle cx="50" cy="50" r="40" stroke="#000" stroke-width="3" fill="red"/></svg>

Command:

npx svgo --multipass ciricle.svg 

Actual: svgo makes no change.

Describe the solution you'd like

Expected: The cleanupEnableBackground plugin should remove enable-background and the style attribute.

Describe alternatives you've considered

I have removed these style manually from my SVG assets.

Additional context

Adobe Illustrator injects this style attribute into SVG files.

MDN has this style marked as deprecated and unsupported:

Note: As a presentation attribute, enable-background can be used as a CSS property.
