Implement unmarshal metrics with jsoniter (#5433)
* Implement unmarshal metrics with jsoniter * Implement unmarshal metrics with jsoniter AND add test file * add unit testing * add unit testing * git rebase main * do a matrix testing for all 8 cases for a combination of these 3 bool options. * some func is deprecated * go imports * go imports * Update change log * generate the 8 cases per tested func to avoid repeating test case definition * 1. Remove instrumentationLibraryMetrics and instrumentation_library_metrics. 2. Some functions move to pdata/internal/json 3.Ignore unknown fields and have a debug log for them * add test unit * update CHANGELOG * remove the new API AND reuse the other API NewJSONUnmarshaler * update CHANGELOG * update CHANGELOG * go mod tidy * remove unnecessary return true on the default branch
