HPCC-8616 Enable generating xml from xsd with configurator

Implementation:
1) configurator and libjlib.so
    Generally put external configurator and libjlib.so in a directory in one of following two ways:
    1.1) provide -DCONFIGURATOR_DIRECTORY=<directory>
    1.2) create directory "configurator" in the <HPCC Platform> parent directory
    configurator and libjlib.so can be built from project "HPCC-Configurator"
 2) Create a new directory <HPCC-Platform>/docs/Automation
     xsd files are copied to <build>/docs/Automation/xsd/
     xml files are generated to <build>/docs/Automation/xml/
 3) There is a cmake option "-DUSE_DOCS_AUTO" which is set to "OFF" by default.
     To start generate xml with configurator need this option set to "ON"

note: initfiles/componentfiles/configxml/esp_service_wsecl2.xsd is skipped since it has error when run through configurator.
