Fix test framework crossgening (#42874)

The recent change that replaced direct invocation of crossgen and
crossgen2 for crossgening framework assemblies for coreclr tests by
r2rtest tool usage has ommited the --release and --large-bubble
arguments. These correspond to the former -O and --inputbubble crossgen2
commands and should be present.

This also fixes failures in running tests with the crossgened runtime.
Many tests were failing with the error `Could not execute the method
because either the method itself or the containing type is not fully
instantiated.`

So while there is a problem to investigate related to debug flavor of
crossgening, this PR fixes the options.
