Subject: Make SourceMap a value type (#2812)

* #include an absolute path didn't work - because paths were taken to always be relative.

* Moved JSON source map writing logic to JSONSourceMapUtil.

* Use ArtifactHandler to read/write SourceMaps.
Use ObjectCastableAdapter to hold SourceMap
Only serialize SourceMap <-> JSON on demand.

* Make some types swappable.

* BoxValue impl.

* Added asBoxValue.

* Remove const get funcs.

* Fix typo in asBoxValue.

* Fix another typo in asBoxValue.

* Slightly simplify conversion to blob of SourceMap.

* Small fix for asBoxValue
