406 animate the command menu button (#10305)

Closes https://github.com/twentyhq/core-team-issues/issues/406

- Added animation on the Icon (The dots rotate and transform into an a
cross)
- Introduced a new component `AnimatedButton`. All the button styling
could be extracted to another file so we don't duplicate the code, but
since `AnimatedLightIconButton` duplicates the style from
`LightIconButton`, I did the same here.
- Added an animate presence component on the command menu to have a
smooth transition from `open` to `close` state
- Merged the open and close command menu button
- For all the pages that are not an index page or a record page, we want
the old behavior because there is no button in the page header to open
the command menu
