[TASK] Update to Lit v2-rc1

Lit is the umbrella term for the next major
lit-html (v2) and lit-element (v3) versions.
Therefore we will refer to these components as
*Lit* in TYPO3 from now on as well.

These two libraries also have been migrated into
a single entry point module named `lit`.
It is officially described as:
> The main module exports the core pieces needed for component
> development: LitElement, html, css, and the most

lit-html v2 and lit-element v3 are mostly compatible
to the previous major versions. Main changes are

 * Deprecation of the `lit-element` entry point in
   favor of the new `lit` module
 * @internalProperty changed to @state
 * shadow css declaration via static property
   instead of static getter method
 * The CSSResult type declaration is gone
 * Directive (currently unused in TYPO3) API has changed

Related testing framework change is:

Commands used:

  rm -rf typo3/sysext/core/Resources/Public/JavaScript/Contrib/{@lit,lit-element,lit-html,lit}/
  yarn add lit@^2.0.0-rc.1 lit-html@^2.0.0-rc.2 lit-element@^3.0.0-rc.1
  yarn add --dev rollup@^2.32.0 @rollup/plugin-replace
