[msd-vsl-gc] Modify ringbuffer helper functions.

Adds ringbuffer ReserveContiguous helper.

We will want to write blocks of instructions contiguously,
such as EVENT WAIT LINK, otherwise we would have to add additional
LINK commands in between to wrap back to the start of the ringbuffer.

Also changes Overwrite32 to take an offset rather than a relative
negative offset.

Next CL will use these.
