Remove object tracking from inflated headers
Add index to header allocation
Pass state to inflated header retrieval where appropriate
Add STATE parameter to object_id retrieval
Pass down state into header word to inflated header
Remove unused lock_ instance variable
Move to index offset in aux word for inflated headers

This ensures that all object header flag handling always happens inside
the object itself and doesn't depend on the inflated header for that.
This ensures we don't need to deference for accessing these bits.
Change object layout to move type bits to front

This has the advantage that we can do a type check in the JIT that
always works because we don't have to consider inflation now anymore
since that doesn't change the flags layout.
Remove unneccessary null check
Remove unused argument for set_inflated_header
Use an aux word meaning since we use aux word to store inflated header

This changes the setup from a boolean inflated flag, to using an
AuxWordMeaning, since that is now more appropriate since aux word is
also where we store the inflated header index.
Also add the size check for C-API handles
Move C-API handling into ObjectMemory

This is a better place, since ObjectMemory is concerned with memory
management and handle management falls under that. Also makes it
consistent with where InflatedHeaders are managed.
