refactor: Phase-field and damage solid model cleanup, refactor

[frankfeifan]

To remove dead codes, unify duplicated logic, rename unclear variables, and decouple crack model type from decomposition scheme to enable more options of the phase-field model.

• Remove unnecessary macros in the solver and damage model
• Unify LocalDissipationOption into a constitutive-level definition
• Add FractureModelType (Brittle/Cohesive/Nucleation), and decouple it from decomposition scheme to allow for more phase-field model combinations, e.g.,
  - Brittle + Linear (AT1)/Quadratic (AT2) + No decomposition/Spectral/VolDev
  - Cohesive + Linear + No decomposition/Spectral/VolDev
  - Nucleation + Linear + No decomposition
• Add check for invalid combinations (Nucleation+Spectral, Cohesive+Quadratic, etc.)
• Update existing phase-field xml decks and add new examples
• Enable co-existence of no-phase-field regions (only solid mech, and no damage dof) and phase-field regions. The previous code will complain about empty damage dof set even the regions are not defined in PhaseFieldFracture or PhaseFieldDamageFEM.
• Add viscous regularization for the phase-field equation
• Rebaseline integrated tests

Nice cleanup

[frankfeifan]

Added a few well-known benchmark examples in inputFiles/phaseField/benchmark which can be used for future phase-field documentation.

A short report summarizing these examples is attached here:
