Add missing case for constrained gsharedvt call. (dotnet#92338)

dotnet@1b788f4
added a new value to our MonoRgctxInfoType enum type, but appears
that all cases where not full adjusted. Running System.Buffers tests
in full AOT hits the assert in info_equal about missing case,
https://github.com/dotnet/runtime/blob/0dc5903679606b072adac70a268cdb77d1147b3e/src/mono/mono/mini/mini-generic-sharing.c#L2908.

This commit adds the new enum value and align handling similar to other cases added
by that commit.
