v3dv: rewrite dirty state handling
The current implementation assumed that we would clear all dirty state
after we have emitted a pipeline, but that is not always true. In
particular, we don't emit blend constants unless we need them, so we
can't clear its dirty bit until we have bound a pipeline that actually
requires them.
The change implemented here has individual emit functions clear pipeline
states they hadle as they emit the corresponding state and we clear
the dirty pipeline bit at the end.
This fixes some CTS pipeline blend tests where we have multiple draws
with blending and only some of them require blend constants. In this case,
the original behavior would clear the blend constants dirty bit on draw
calls that don't actually emit blend constants (because they don't need
them), making the later draw calls that do need them fail because they
don't emit them either (since the previous draw calls cleared the dirty
bit).
