Bump lit and lit-labs to latest

[steverep]

Proposed change

Upgrades lit to 2.6.1, @lit-labs/motion to 1.0.3, and @lit-labs/virtualizer to 1.0.1.

• Removed the associated resolutions as they are not needed anymore (MWC just requires lit@^2.0.0 now)
• Removed the patch for event-target-shim (that sub-dependency is upgraded and now exports the EventTarget class)
• Fixed an import change for VisibilityChangeEvent

Note that this PR + #15000 results in some duplicates from app-datepicker because we have a version dependent on MWC 0.25.3 (which has been deprecated). Those will go away when that package is upgraded next.
