Setting the C++ standard explicitly in the project configurations.

Before anything else, so that defaults in AtlasLCG and AtlasCMake
would not be the ones taken.

This way making sure that COOL and CORAL would be available to WorkDir projects
building packages against an installed release. Without WorkDir having to do
hacks to make it happen. This is to address ATLINFR-4302.

Normally, when using an "offline build", those flags get set up project-wide.
But Point-1 projects only include the definitions of the exported targets,
without the use of the DetCommon project files. For such downstream projects
to work without hardcoding how they should use these exported targets, the
XAOD_STANDALONE and TRIGCONF_STANDALONE compiler flags are put explicitly
on the TrigConfData library.

Much of the rest of the DetCommon libraries (that care about these flags
anyway...) depend on TrigConfData, so I didn't add this anywhere else.

DetCommon does not depend on the `generators` component of LCG. So don't
request it to avoid configuration failures when compiling against an
installed releases.

The project configuration is essentially copied from `AthDataQuality`.

Took some updates from the 21.0 branch that somehow never made it here,
and in general updated the project to the same layout as all the other
projects. Plus updated the readme file to make it a bit more usable...
