ISO19111: remove PROJ.5 specific format for CRS (refs #1214)

As discussed in https://github.com/OSGeo/proj.4/issues/1214#issuecomment-452084720,
the introduction of a new PROJ.5 format to export CRS using pipeline/unitconvert/axisswap
as an attempt of improving the PROJ.4 format used by GDAL and other products is
likely a dead-end since it is still lossy in many aspects and can cause confusion
with coodinate operations.

Consequently the PROJ_5 convention will be identical to PROJ_4 for CRS export.

Note: on the import side, I've kept the code that could parse unitconvert and
axisswap when building a CRS definition from a pipeline. It is there as a hidden
feature as it was kind of a tear to remove that code in case it might still be
useful...
