Breaking: #73611 - Removed ResourceCompressor relative path methods

See Issue #73611

Description

The methods ResourceCompressor::setInitialPaths() and ResourceCompressor::setRelativePath() have been removed.

Impact

Calling one of the methods above will result in a fatal PHP error.

Affected Installations

Any TYPO3 instance with custom extensions manually using the ResourceCompressor instead of using the PageRenderer API.

Migration

Simply remove the methods from the affected code, as these methods are not needed anymore. All calculations for the paths are now done automatically.
