Previously, only simple, single-slot transclusion worked on upgraded components.
This commit fixes/adds support for the following:
- Multi-slot transclusion.
- Using fallback content when no transclusion content is provided.
- Destroy unused scope (when using fallback content).
Fixes#13271
`Object.assign` is not available in all supported browsers and one had to
provide a polyfill. This commit replaces `Object.assign` with the spread
operator (`...`), which TypeScript will transpile to ES5-compatible code.

Destructuring of the form:
function foo({a, b}: {a?, b?} = {})
breaks strictNullChecks, due to the TypeScript bug https://github.com/microsoft/typescript/issues/10078.
This change eliminates usage of destructuring in function argument lists in cases where it would leak
into the public API .d.ts.
toString() from DefaultKeyValueDiffer is only used in tests and should not
be part of the production code. toString() methods from differs add
~ 0.3KB (min+gzip) to the production bundle size.
With 4.2, we introduced the min and max validator directives. This was actually a breaking change because their selectors could include custom value accessors using the min/max properties for their own purposes.
For now, we are rolling back the change by removing the exports. At the least, we should wait to add them until a major version. In the meantime, we will have further discussion about what the best solution is going forward for all validator directives.
Closes#17491.

PR #17551 tried to roll this back, but did not remove the dead code. This failed internal tests that were checking that all declared directives were used.
This PR rolls back the original PR and commit the same as #17551 while also removing the dead code.
