Following ij_formatter_{off,on}_tag pair

[njokipal]

At the moment ktlint has the per-line // ktlint-disable marker comments for disabling rules, which is nice.
Currently, I write my code with IntelliJ IDEA, that offers the notion of formatter off and formatter on tag pair, which default to //@formatter:off and //@formatter:on comment pairs. These values may also be configured in an EditorConfig file using ij_formatter_off_tag and ij_formatter_on_tag keys.

In my code, I have some very long lines with some look-up data, like lists/maps of hundreds of static values, which I deem aren't really that important to be visible at once, for them to follow the max_line_length value set using EditorConfig value. I'll wrap those blobs of code with the formatter off/on pair, and IDEA won't auto-format them for me.

For ktlint, I have to insert additional /* ktlint-disable max-line-length */ and /* ktlint-enable max-line-length */ comment pair around the the no-format block, which seems redundant.

Could there be a possibility to obey the no-formatting tags or define a set of no-format boundaries keys setting for using non-ktlint-disable?

Expected Behavior

ktlint would obey existing/provide additional no-format boundary comments

Current Behavior

Additional // ktlint-disable max-line-length,... needs to be added for each row inside already in the no-format block for the IDE

Additional information

• Current version of ktlint: 0.40.0

This should be marked as an enhancement. The request seems very valid to me although I do not use those markers myself.

In case .editorconfig property ij_formatter_tags_enabled is true than handle tag ij_formatter_off_tag same as ktlint-disable and ij_formatter_on_tag same as ktlint-enable. This only requires a change in the SupressedRegionLocator.

However this should only be done after the Indent rule has been refactored and no longer works on the entire file (see #631).
