fix: Standardisation of incorrect sub-group creation errors

[MelReyCG]

This PR aim to standardise the behaviour & log message when user attempt to create in a given node:

1. Non-node content, like raw text,
2. Unexpected XML sub-node (thus, unexpected Group type name request in Group::createChild())

---

1. Non-node content

For instance, before this PR, entering raw text in a <ElementRegions> resulted in a misleading message:

***** Rank 0: KeyName () not found in ObjectManager::Catalog

We would now have:

***** Rank 0: Error in node named "ElementRegions" (staircase_co2_wells_3d.xml, l.124): GEOS XML nodes cannot contain text data nor anything but XML nodes.
Erroneous content: "lorem ipsum"

If a Group type would need this kind of sub-content later, we would have to manage this data, and silence this error for the case it would be allowed.

---

2. Unexpected sub-node

For instance, before this PR, adding a wrongly spelled <Perforation> , or any unexpected name, in a <InternalWell> a resulted in:

***** LOCATION: /data/pau901/SIM_CS/users/MelvinRey/WorkEnv/GEOSX_repos/GEOS/src/coreComponents/mesh/generators/WellGeneratorBase.cpp:90
***** Controlling expression (should be false): true
***** Rank 0: Unrecognized node: Prerforatio

We would now have:

***** ERROR
***** LOCATION: /data/pau901/SIM_CS/users/MelvinRey/WorkEnv/GEOSX_repos/GEOS/src/coreComponents/mesh/generators/WellGeneratorBase.cpp:81
***** Controlling expression (should be false): childKey != viewKeyStruct::perforationString()
***** Rank 0: The tag "Prerforatio" is invalid within well_producer1 (staircase_co2_wells_3d.xml, l.74). Please verify the keywords spelling and that input file parameters have not changed.
All available tags are: Perforation

Previously, error of this kind were not always managed properly. Also, various Group types messages were not standardized nor indicating available sub-type names.

---

This PR also improve how wrong character are underlined:

***** Rank 0: Input string validation failed at:
  "well  Region1"
       ^^
  Expected format: Input value must be a string that cannot be empty and contains only upper/lower letters, digits, and the characters  . - _

It was broken for some cases by the PR #3403, so I fixed that and also improved it by underlining the (first) whole sequence of wrong characters.

[wrtobin]

looks like there are some changes from geos internal string to specifically std::string on some interfaces, is there a reason this is needed?

[MelReyCG]

@wrtobin half mistake, half in place pratices in ObjectCatalog.hpp (this last one has a lot of old std::string).
We have a lot of std::string in coreComponents, but that is a subject for another PR.
