Enhancements to MCS dumpMap (#52412)

I've been trying to correlate methods in SPMI collections with methods
seen in profile data (say perfview). But for generic classes or generic
methods this is not easy.

To make it more feasible, in the "extra query" mode, get the names of
all the generic parameters, and then add these to the class name in MCS's
dumpMap output.

Also dump out the jit flags, so it's easier to find a particular instance
if the method was jitted more than once.
