[query] Remove HailStateManager

[ehigham]

This change removes the need for the HailStateManager by storing the reference genome on the TLocus and parsing the reference by name when the IR is parsed.
There should be no behavioural changes herein - the ir can't compile if the refererence is unknown - all I'm doing is parsing it earlier.

This change has low security impact.
