For feature parity with initial preambles.
Previously, continue preambles were for GFX6 only, but this is
about to change in the next commits.

Skipping the continue preamble can allow other processes to mess
up some registers set by the current process.
Originally, we could omit generating the continue preamble when
no shader rings were used, because the register initialization
happened at the beginning of every main cmdbuf. However, this
isn't the case anymore.

This introduces tracking of the required semaphore values in pipelines,
which is then propagated to cmd_buffers on bind. Each queue also keeps
track the maximum count it has waited for, so that we can avoid the waiting
overhead once all the shaders are loaded and referenced.
