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:

@jhuang2601 @victorapm, the refined versions are now provided in GEOS-DEV/GEOSDATA#3

Thanks Frank!

Should m_damageGrad also be updated?

[frankfeifan]

Should m_damageGrad also be updated?

So far m_damageGrad is only used in the PhaseFieldPoromechanicsSolver, so it's not mapped here in this solver for pure solid. That said, it's worthwhile to consolidate the two interpolation kernels in the poromechanics solver and this solid solver into one. The tradeoff is just to write an additional array for each outer iteration, which should be trivial.

[jhuang2601]

Also interpolates damageGradOnMaterial?

Same comment above.

Needs a code owner review from @bd713 and/or @rrsettgast
