Rune extensions micro-optimizations (#3910)

Browse Source 
* Add benchmarks for potentially optimizable RuneExtensions

* Add new RuneExtensions.DecodeSurrogatePair benchmark implementation

Avoids intermediate heap array allocations which is especially nice when the rune is not surrogate pair because then array heap allocations are completely avoided.

* Enable nullable reference types in RuneExtensions

* Make RuneExtensions.MaxUnicodeCodePoint readonly

Makes sure no one can accidentally change the value. Ideally would be const value.

* Optimize RuneExtensions.DecodeSurrogatePair

* Remove duplicate Rune.GetUnicodeCategory call

* Add new RuneExtensions.IsSurrogatePair benchmark implementation

Avoids intermediate heap allocations by using stack allocated buffer.

* Optimize RuneExtensions.IsSurrogatePair

* Add RuneExtensions.GetEncodingLength tests

* Optimize RuneExtensions.GetEncodingLength

* Optimize RuneExtensions.Encode

* Print encoding name in benchmark results

* Rename variable to better match return description

* Add RuneExtensions.EncodeSurrogatePair benchmark
