Renamed ace/mode -> ace/modes

Enable Watcher editor to parse XJson using XJsonMode

Import JSON highlight rules in XJSONHighlight rules

Exporting console_lang through the es_ui_shared/public barrel caused the XJsonMode to imported to a index_management too and any other plugin that may
import something from that directory. console_lang was moved to it's own top level directory es_ui_shared/console_lang.

We also included a mock for tests using XJsonMode to import from console_lang.

Console Jest tests were still failing because they did not mock out the raw-loader imported worker file

Upon entering the advanced watcher creation view, the JSON should be scanned for triple quote expansion

Editors had github theme, which diverged from the textmate theme used in Console and SearchProfiler

Slight refactor to the logic for using XJSON mode. Created an adhoc hook for wrapping the
logic of useState and moved lanugage util imports there too to reduce the number of imports
in both the watcher form and simulate tabs in advanced creation.

x-json worker is currently only used inside of x-pack. Also testing
for if this will fix the CI/prod build
