ToolsPanel: Allow additional props on ToolsPanel

[aaronrobertshaw]

Description

Reintroduces the ability to apply custom props to a ToolsPanel.

It was previously removed to avoid expose Grid component props. Credit for the change goes to @ciampo.

See discussion here: #35621 (comment)

How has this been tested?

1. Manually added custom props to the ToolsPanel within the Storybook example and confirmed props were applied.
2. Confirmed that the ToolsPanel still functions correctly in the block and site editors.

Enhancement.

Checked in post and site editors. All Tools Panel support controls work as expected.

I added a random prop to the block support Tools Panel and it was passed as expected:

Code changes LGTM 🚀 Once again, thank you for addressing this feedback so promptly!

I wonder if this change deserves a little CHANGELOG entry
