Subject: [PATCH 1/2] [Devourer] Tune Void Metamorphosis fury drain constants

First second after entering meta drains 10/s (not 15), and reduced drain
while casting Collapsing Star / channeling Void Ray is 0.127x (not 0.15x).
Measured from WarcraftLogs per-tick drain across current raid logs. The
15 + 1.455*exp(0.075*s) curve itself matches the logs and is unchanged.
