Mercator projection, but with subtlely different parameters (fixes https://github.com/OSGeo/gdal/issues/2087)

Related to https://github.com/OSGeo/proj-datumgrid/pull/66
Tune operation search so that it can work with Geog2D <--> VertCS for commandline

Relates to https://github.com/OSGeo/proj-datumgrid/pull/65 ,
https://github.com/OSGeo/proj-datumgrid/issues/22
As EPSG has no entry for it, we create a grid_transformation, as well as a
dedicated area of use based on the extent of the grid, under the PROJ authority.
With the hope to be able to remove it once EPSG has an entry...

inv constructs
Given an initial pipeline with
+step +proj=hgridshift +grids=foo
+step +proj=vgridshift +grids=bar
+step +inv +proj=hgridshift +grids=foo
Transform it as
+step +proj=push +v_1 +v_2
+step +proj=hgridshift +grids=foo +omit_inv
+step +proj=vgridshift +grids=bar
+step +inv +proj=hgridshift +grids=foo +omit_fwd
+step +proj=pop +v_1 +v_2
So as to avoid doing a double application of the hgridshift.

Inspired from syntax of https://github.com/OSGeo/PROJ/pull/453/files
but 'rebased' on top of previous commit that cleans up the pipeline implementation
Different situations:
- +omit_fwd:
the step when followed in the forward path will be omitted
the step when followed in the reverse path will be executed
- +omit_fwd +inv:
the step when followed in the forward path will be omitted
the step when followed in the reverse path will be executed (with the inv method)
- +omit_inv:
the step when followed in the forward path will be executed
the step when followed in the reverse path will be omitted
- +omit_inv +inv:
the step when followed in the forward path will be executed (with the inv method)
the step when followed in the reverse path will be omitted
This will be used in the next commit to optimize constructs like
+step +proj=hgridshift +grids=foo
+step +proj=vgridshift +grids=bar
+step +inv +proj=hgridshift +grids=foo
Such steps are used for CRS to CRS transformations where applying the vertical grid
requires to do a transformation to an interpolating CRS. One can notice that
in the last step will just restore the horizontal coordinates before the first step, so
doing an inverse hgridshift is overkill.
So that could be optimized as:
+step +proj=push +v_1 +v_2
+step +proj=hgridshift +grids=foo +omit_inv
+step +proj=vgridshift +grids=bar
+step +inv +proj=hgridshift +grids=foo +omit_fwd
+step +proj=pop +v_1 +v_2
In the forward path, this will be equivalent to:
+step +proj=push +v_1 +v_2
+step +proj=hgridshift +grids=foo
+step +proj=vgridshift +grids=bar
+step +prop=pop +v_1 +v_2
And similarly in the reverse path, this will be quivalent to:
+step +proj=push +v_1 +v_2
+step +proj=hgridshift +grids=foo
+step +inv +proj=vgridshift +grids=bar
+step +proj=pop +v_1 +v_2

not mess the derivingConversion object of the original object (fixes #1736)
normalizeForVisualization(), promoteTo3D(), demoteTo2D(), alterGeodeticCRS(),
alterCSLinearUnit() and alterParametersLinearUnit() all used the object
returned by derivingConversionRef() to create a new ProjectedCRS. While doing
so, this caused the derivingConversion of the original object to have its
targetCRS set to the object returned by normalizeForVisualization() and similar.
If that object died, then the weak pointer would be reset, and the original
ProjectedCRS() has now its derivingConversionRef()->targetCRS() nullptr
So bottom line is use derivingConversion() for anything that is not pure
reading !!!
This is confirmed to be the fix for the QGIS scenario in
https://github.com/qgis/QGIS/issues/30569#issuecomment-540060919
In QGIS use case, the issue arised when using a projected CRS with a non-GIS
friendly axis (that is where normalizeForVisualization() created a new projectedCRS)

The 'publication_date' naming is from OGC Topic 2, and hasn't been yet adopted
by the EPSG dataset.

This is invalid WKT, but GDAL 2.4 used to accept it and make a reasonable
use of it...
Currently we default it to 0 which is non sensical. Better use 1 as GDAL 2.4
did, and emit a warning.
Other fix: proj_create_from_wkt() was documented to operate by default in
non-strict validation mode, but it was actually in strict mode. So do as
documented.

arbitrary number of steps (fixes #1632)
EPSG:9103 (NAD27 to ITRF2014 (1)) is now handled.
Note:EPSG:9104 (NAD27 to ITRF2014 (2)) is not currently, since it uses
for step EPSG:8861 (NAD83(HARN) to NAD83(FBN) (1))
an unsupported transformation method (NADCON5 (3D), EPSG:1075).

In recent commits, we added a generalize_proj_crs_create_bound_vertical_crs_to_WGS84()
function, but there are situations where more accurate results can be obtained, if
instead of specifying WGS84 as the hub CRS, the user can specify the exact hub CRS.
For example the GEOID2018 grid is against NAD83(2011).
So replace this function with proj_crs_create_bound_vertical_crs()

Note: a hack has been added into customizations.sql to cancel deprecatation
of USA geoid2012 grids by geoid2018 grids, as the later are not yet available
