* Artifact publishing can happen at any time from the printing of directive till the end of run configuration execution,
  so dump shouldn't be stored in the test-specific folder, which can be deleted at test tear-down. Now the root of
  Teamcity temp directory will be used for dumps.
* Publishing directive should be printed after the dump is created, not before it, so that Teamcity can definitely find
  the file at advertised place.

Also: json5 allows keys to be single-quoted strings.

This PR re-implements extraction of '$id' and '$schema' properties from
the root level of JSON files. The new implementation is based directly
on JsonParser and does not require a full Psi tree to be built.

The change improves the performance of the JsonSchemaFileValuesIndex
which sometimes makes a substantial part of the overall indexing time.
Observed change: from 20 second to 3.5 second spent indexing JSON.
