[xml editor] make artificial editor lines configurable

[rhoehener]

• these lines often look to me like mistakes until i notice that they are artificial
• the lines tend to shift after loading:
  • makes the content hard to scan quickly when stepping through file search results
  • causes wrong line to be selected when the lines shift right before the click (I often delete the wrong line with Ctrl + D)

The 2nd space between line 1 and 2 is a bug in Platform. Can you please report it to https://github.com/eclipse-platform/eclipse.platform.ui/issues with steps to reproduce?
The question of showing "code minings" annotations/actions or not needs refinement: there are multiple layers on which this could be done: per annotation, per language server, per language, for all editors...

@rhoehener if you dont like codelens yiu can disable it for xml with the préférences XML / Code Lens

[rhoehener]

@angelozerr aah thank you! maybe consider making the options discoverable with an icon next to the line number (like the java editor does for compiler messages):

@mickaelistria ok i will (i'm fine with just disabling codelens though, both empty lines disappear)

It appears that the WWD setting also affects the WTP XML editor, so maybe it's still worth investigating from the WWD side as well.

In practice, code-minings are enabled for a file-type, not for an editor.

ok, just a bit confusing to me when the setting is in the WWD section and not in the file-type section. after i learned that the WTP XML formatting settings are completely independent from the WWD XML settings.
