[PWGDQ] adding generator to trigger all inclusive quarkonia in pp (#2466)

* [PWGDQ] possiblity to trigger all quarkonia

* possibility to pass rejection factors by string

* [PWGDQ] adding generator to trigger all inclusive quarkonia in pp

* clang format

* small fix

* update with possibility to choose which decay table we want

* small fix for failing tests

* fix missing tests

* fix more failing tests

* fixing another small bug for EM, hoping it is the last

* correct fix

* removing all PWGEM files
