Fix issues with passing 16-byte structs on Arm64
Properly track the GC pointers that are being loaded/stored or copied from these pass by value structs.
Implements passing 16-byte value types in the outgoing stack area, previously not implemented.
Added utility method getJitGCtype for converting the VM's CorInfoGCType to the JIT's var_types enum
Added utility method getStructGcPtrsFromOp to examine a GT_LDOPB or GT_LCL_VAR
that represents a 16-byte struct and get the GC layout information
Allow LSRA to pick two consecutive registers to pass 16-byte structs on the stack
Added utility methods checkAndAssignInterval and checkAndClearInterval to handle the
second register used to pass arguments on ARM64.
