WIP: ENH: add 'outputCoeffs' and 'extendedOutput' options to forceCoeffs

ENH: add 'extendedOutput' option that allows to output all constitutents of all force coefficients, i.e. total, pressure, viscous, and porous

ENH: add 'outputCoeffs' option to allow to select coefficients to output

ENH: remove redundant computations for porosity constituent when the option porosity=false

DOC: improve header file and function declaration docs

BAKW: test backward compatibility and functionality in comparison to v1906 by using simpleFoam/motorBike and simpleFoam/bump2D.

Tests have involved:

• Serial runs
• Parallel runs
• Serial restart
• Parallel restart
• Only binData = on (parallel)
• Only writeFields = on (parallel)
• Only extendedOutput = on (parallel)
• binData and extendedOutput = on (parallel)
• writeFields and extendedOutput = on (parallel)
• outputCoeffs and extendedOutput = on for arbitrarily chosen (Cd CmRoll Cl) (parallel and serial)
