[NFC][regalloc] Move evict advisor initialization before VRAI 

This is because a subsequent patch will propose obtaining the VRAI from
the advisor, which will enable feature caching for the ML advisor, for
better compile time. Making this change first as it's both innocuous and
keeps the future patch to be reviewed small.
