Replace non-existent functions: civicrm_initialize(), drupal_set_title(), and so on

If no one has complained of fatal errors by this point... is that code even reachable?
Completely unused code should probably be removed rather than updated IMO.

Created a patch for the issue mentioned, please review.
Thank You.

@Ranjit1032002 there are a few problems with the patch:

- WebformCivicrmPostProcess::adjustPageBreak() doesn't exist.
- WebformCivicrmPostProcess::checkBillingPagination() doesn't exist.
- Replacing drupal_set_title() with just $this->t('...) doesn't do anything. You need to assign it to something and figure out a way to alter the title.
- webform_submission_access() doesn't exist.
- WebformCivicrmPostProcess::preprocessComponentsForm() doesn't exist.

Please put in a bit more thought into the PR before submitting it.

The only thing that potentially works in this PR is putting in \Drupal::service('civicrm')->initialize();.

After fixing things, I suggest testing out the PR first before posting it for others to review or test.

I dont see civicrm_initialize() anywhere in webform_civicrm.module.

@Ranjit1032002 Are you using the latest version?

I've raised a PR to fix this - https://github.com/colemanw/webform_civicrm/pull/870

The call to civicrm_initialize() have been removed in commit d8518917, done one month ago, but it has been pushed on the development snapshot and probably no new releases have been created.

Actually -> I have issued a new release.
