[errorReport][hook-callback.js] errorReportBaseUrl is not based on hook.parameters.baseURI

[t2ym]

[errorReport][hook-callback.js] errorReportBaseUrl is not based on hook.parameters.baseURI

Root Cause

• The initial code assuming location is at the same directory as the entry page is inapplicable to these cases
  • IFrame pages that are not in the same directory as the entry page
  • Web worker scripts that are not in the same directory as the entry page
  • [For potential support in the future] Dynamic top pages that are not in the same directory as the entry page
