RFR: 8356044: Use Double::hashCode and Long::hashCode in java.vm.ci.meta

[Shaojin Wen]

Similar to #24959 and #24971 and #24987, AbstractProfiledItem/PrimitiveConstant in java.vm.ci.meta can also be simplified similarly.

Replace manual bitwise operations in hashCode implementations of java.vm.ci.meta.AbstractProfiledItem/java.vm.ci.meta.PrimitiveConstant with Long::hashCode/Double.hashCode.
