[dv,mem_bkdr_util] Move otp specific code to otp_ctrl

Change the code to take a handle to the OTP mem_bkdr_util instance,
and use that to perform plain reads and writes to the underlying
memory.

The otp_ctrl code in mem_bkdr_util was making this utility to become
top-specific, which is wrong for a generic utility, and caused build
failures.

Change the uses of the affected functions in top_earlgrey dv code.

The main change is the move of hw/dv/sv/mem_bkdr_util/mem_bkdr_util__otp.sv
to hw/ip_templates/otp_ctrl/dv/ev/otp_ctrl_mem_bkdr_util_pkg.sv, and
changing the functions to take a mem_bkdr_util handle. For some reason
git didn't detect this as a move.
