CI: Add running RTLMeter workflow on selective PRs (#6271) 
Runs RTLMeter on PRs if the PR has the 'pr: rtlmeter' label applied to
it. This should make it easy to selectively require the RTLMeter
workflows to pass on a PR that is potentially invasive, per our own
judgement.

Unify the two DFG cycle finding algorithms. (#6262) 
Both V3DfgBreakCycles.cpp and V3DfgDecomposition.cpp used to contain an
implementation of the same algorithm to color strongly connected
components. Now there is only one, and it lives in V3DfgColorSCCs.cpp.

Merge DFG components made acyclic into the original acyclic sub-graph. (#6261) 
After making a cyclic DFG component acyclic, merge that component back
into the acyclic sub-graph of the input graph. This enables optimizing
through the components that were made acyclic in their larger context.

Fix partial DFG conversion of concat assignments (#6255) 
When we had a `{a, b} = ...`, and the DFG conversion of `a = ...`
succeeded, but `b = ...` failed, we still used to include `a = ...` in
the DFG, which then caused a spurious multi-driver error for `a` on
a subsequent DFG pass, as the original `{a, b} = ...` was still present
in the Ast, but we also had the extra `a = ...` from converting out of
DFG on the previous pass.

In this patch we only convert assignments with a concatenation on the
LHS, if all target LValues can be converted into DFG.

This is the proper fix for #4231
