DIMAP: Correctly set RPC origin for SPOT, PHR and PNEO

[tbonfort]

Rework #5725 to set RPC origin from the sensor profile instead of from the ImagetoGround_Validity_Domain

For reference: #5716 and https://lists.osgeo.org/pipermail/gdal-dev/2015-June/042090.html

Good idea. ImagetoGround_Validity_Domain can theorically starts at a non origin position.

@tbonfort anything missing for this PR to be mergeable ?

[tbonfort]

@rouault I'm off work this week, this pr can be included as is if you want to include it in the 3.7 release candidates. I still have a small batch of refactorings with no functional change to add to it but they can come in a subsequent pr.

[tbonfort]

ha, sorry, I just saw Im late to the game as the rc has already been released. So this pr is a candidate for rc2 if it were to exist but does not warrant an rc2 as of itself

[rouault]

Merging this, and tagging it for backport for 3.7.1

@tbonfort @Lunyxis @jguinet A user is reporting in https://lists.osgeo.org/pipermail/gdal-dev/2023-July/057505.html that it seems that this changes causes a regression with some PNEO images whose ImagetoGround_Validity_Domain.FIRST_COL/FIRST_ROW are negative

@rouault thanks, I've followed up off list with him and will report back with the outcome
