PSR-12 compliancy

This reverts commit 9fa3dc94.

Rename Utils\HTTP::getSelfHostWithoutPort() to Utils\HTTP::getSelfHostWithNonStandardPort(), change the logic, and reimplement Utils\HTTP::getSelfHost() to depend on use the former. Complete the tests to include the case of port 443 while using HTTPS.

(being respectful with occurences that might change the behaviour, i.e. default database prefixes)

Move SimpleSAML_Utilities::getSelfHost() to SimpleSAML\Utils\HTTP::getSelfHost() and deprecate the former.

Move SimpleSAML_Utilities:::getBaseURL() to SimpleSAML\Utils\HTTP::getBaseURL() and deprecate the former.

Replace uses of utilities::selfURLhost() followed by config->getBaseURL with a call to utilities::getBaseURL().
