pldm: Add parsing JSON for Numeric Effecter PDR

According to spec DSP0248_1.2.0: 28.11 and effecter_pdr.json, parse JSON and generate PDR
structure.

In addition:
 1. move the parsing generateNumericEffecterHandler method to pdr_numeric_effecter_pdr.hpp.
 2. test/libpldmresponder_pdr_state_effecter_test.cpp renamed
test/libpldmresponder_pdr_effecter_test.cpp.

Tested with JSON files:
