Improve performance of cgroup access (#21229)

Currently, we create a CGroup instance on each request for getting
used or total physical memory. This has an extra cost of finding
filesystem paths of the current cgroup files. I have found that
if we do the initialization just once, the performance of getting
the used or total memory in a tight loop improves 22 times.

Accidentally, I was also looking into a perf regression in the
ByteMark.BenchBitOps test that was observed in the past, seemingly
related to the recent change to the way we get the used memory.

the change in this commit.

In the test we have a synchronized method so we change the return node to
return a comma that include a call to HELPER.CORINFO_HELP_MON_EXIT.
If the rightmost comma expression doesn't have GTF_DONT_CSE,

Make type comparisons more general purpose (#20940)

This has two parts:

## Part 1
CoreRT represents native type handles differently from CoreCLR - on CoreCLR, `RuntimeTypeHandle` is a wrapper over `RuntimeType` and RyuJIT is aware of that. On CoreRT, `RuntimeTypeHandle` wraps the native type handle, not a `RuntimeType`.

The knowledge is hardcoded in importer when importing the sequence "ldtoken foo / call Type.GetTypeFromHandle" - importer just removes the call and bashes the result of ldtoken to be a reference type. CoreRT had to avoid reporting `Type.GetTypeFromHandle` as an intrinsic because of that.

I'm adding another helper that lets RyuJIT avoid hardcoding that knowledge. Instead of just bashing the return type, we swap the helper call.

## Part 2

Native type handle equality checks need to go through a helper, unless the EE side says it's okay to compare native type handles directly.
