Study how to handle uninstallation of marketplace extension in installer

Study how to remove exported conan recipe from local cache when uninstalling a marketplace extension from installer.

Way 1 (for demonstration):

This can be done by registering an UNDO step for execute operation. An example operation might look like this, assuming "TARGET_INSTALL_DIR" points to installation path  of the component and "QtConanBinary" is set:

component.addOperation("Execute", "workingdirectory=@TargetDir@" + TARGET_INSTALL_DIR, installer.value("QtConanBinary"), "export", ".", "qtcharts/5.12.3@qt/final", "UNDOEXECUTE", installer.value("QtConanBinary"), "remove", "-f", "qtcharts/5.12.3@qt/final");

Way 2:

Could be done using the operations described in QTIFW-1563. qt.tools.conan component would need to register a valid command sequence for removing exported marketplace extension from local cache.
