Switch to using resources in BenchmarksGames tests (#21554)

Embed the following test files as the resources in their corresponding test assemblies:

* regexdna-input25.txt regexdna-input25000.txt in BenchmarksGame/regex-redux

* knucleotide-input.txt knucleotide-input-big.txt in BenchmarksGame/k-nucleotide

* revcomp-input25.txt revcomp-input25000.txt in BenchmarksGame/reverse-complement
