RFR: 8274617: constructor and parameter annotations are not copied to the anonymous class constructor

[Vicente Romero]

Please review this PR which is about propagating constructor and parameter annotations to the anonymous class constructor. Currently we are propagating them to bridge methods which are synthetic. Propagating them to the anonymous class constructor seems sensible given that they are mandated by the spec. Please review also the related CSR,

TIA
