AAIGRID output: remove leading space on each line (fixes #8344)

[rouault]

but put one at end of line.

Esri spec shows an example without leading space:
https://desktop.arcgis.com/en/arcmap/10.3/manage-data/raster-and-images/esri-ascii-raster-format.htm .

Let's align on that

Did you take into account the space before each linefeed in the ESRI style files?

Linefeeds are not required in the specification but the whole data section can be just a single row with space separated values. I think that the idea is to remove all linefeeds and carriage returns and get such a string as a result.

no, hopefully that doesn't matter

ah ok, missed that. Actually that helps making the code simpler (2 line shorter :-)). Doing that then

I believe that it is safer that way even it seems that ESRI is not so strict. I made a test by removing the ending space from an .asc file that was created by ArcGIS Pro, and it could still be opened with ArcGIS Pro.
