Update Microsoft.NETCore.CoreDisTools to version 1.0.1-prerelease-00005 (#19520)

* Update Microsoft.NETCore.CoreDisTools to version 1.0.1-prerelease-00005. Temporarily add a direct reference to the win-x64 and win-x86 runtime packages

* Change Microsoft.NETCore.CoreDisTools package references to the identity package.

Improve formatting of R2RDump.csproj properties.

* Add an ArgumentException to explain the currently faulty behavior where disassembling an R2R image whose architecture is different than the coredistools.dll architecture.

* Add Issue #19564 to the R2RDump.cs Disassembler comment
