Initial support for normalized 'naked' R2RDump output (dotnet/coreclr#20875)

Initial support for normalized 'naked' R2RDump output (dotnet/coreclr#20875)

* Initial support for normalized 'naked' R2RDump output

This change introduces a new option "--naked" that takes output
normalization even further - it intentionally leaves out any
position information to make the output easier to diff between
CPAOT and Crossgen.

One other new option is "--entrypoints" which dumps a plain
list of JITted methods in the R2R executable. This can be used
for comparisons between CPAOT and Crossgen and / or for static
analysis of what methods were actually emitted by the compiler.

* Addressed Zach's PR feedback

1) Added argument consistency check for the invalid combination
"--naked" + "--raw".

2) Added dump of multi-dimensional array lower bounds and sizes
when available.

Thanks

Tomas
