Bug 1852026: refactor getUrlParameter(param, url)

to use JS function URLSearchParams. The result should stay the same, it should not change any behaviour.

The function is used in :
./htdocs/relatedtags.php
./htdocs/tags.php
./htdocs/js/adminusersearch.js
./htdocs/js/export.js
./htdocs/js/privacy.js
./htdocs/js/adminexportqueue.js
./htdocs/artefact/annotation/blocktype/annotation/js/annotation.js
./htdocs/artefact/plans/js/planview.js
./htdocs/artefact/peerassessment/blocktype/peerassessment/js/peerassessment.js
./htdocs/artefact/file/js/filebrowser.js
./htdocs/theme/raw/js/formtabs.js
./htdocs/view/choosetemplate.php

the function updateUrlParameter is used in:
./htdocs/relatedtags.php
./htdocs/js/privacy.js
./htdocs/js/mahara.js
./htdocs/artefact/file/js/filebrowser.js
