[master] RFR: Disable biased locking altogether [v2]

[Roman Kennke]

> In anticipation of eventual removal of biased locking (see JDK-8256425), I'd like to always disable BL in Lilliput. This makes room in the header to put the compressed Klass* in the upper 32 bit. With BL, it would clash with the Thread* there.
> 
> Testing:
>  - [x] tier1
>  - [ ] tier2
