[ibex] Enable bit-manipulation extension

This vendors in the latest version of Ibex supporting the OTEarlGrey
bitmanip configuration and enables this config in Earl Grey. This adds
support for the Zba, Zbb, Zbc and Zbs bit-manipulation sub-extensions
ratified in v.1.0.0 of the RISC-V Bit-Manipulation ISA Extension, as
well as support for the non-ratified sub-extensions Zbf, Zbp, Zbr,
Zbt part of the draft v.0.93 spec.

This resolves lowRISC/OpenTitan#2708.
