Fix preaccumulation error, improve recording of RANS solvers

[oleburghardt]

Proposed Changes

This contributes two algorithmic-differentiation-based fixes;

• Add a missing preaccumulation input to the recording of SetRoe_Dissipation_FD. This may change derivatives as the current recording of this function is likely to be wrong if PREACC = YES.
• Include muT (eddy viscosity) as input/output to the recording of RANS solvers. Since both muT and conservative variables go "on the same level" into the flow solver's Preprocessing (i.e. we cannot think of muT as a derived value from the conservative ones), this should be reflected in the recording. (Also, the debug mode developed in Tape recording debug mode #2442 will complain otherwise ;-)).
  This change does not affect derivative values – especially it does nothing about the circumstance that Preprocessing is based on an initial value of muT, whereas the flow solvers depend on an updated one – but it may clarify things and remove a source of future problems.

Related Work

• Both fixes are a by-product of working on [WIP] Multizone adjoints for turbomachinery #2446
• The tape recording debug mode that can detect such kind of issues (Tape recording debug mode #2442) needs some more features before being ready to be merged.

@oleburghardt if everything is addressed can you resolve the conversations and merge please?

Sure. CodeFactor is complaining about CSolver.hpp (complex code) which I've touched in a commit but which eventually remains unchanged. Forgot to ask during last dev meeting how we should handle it?

You can ignore that warning, It doesn't say what to do so we can't do anything.
