Improvements outputting containers (#2815)

* #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.

* WIP Api improvements around sourcemap/artifact/line-directive.

* Small fix for asBoxValue

* WIP outputting container with multiple artifacts.

* Added ArtifactContailerUtil::filter to produce an artifact hierarchy that only contains "signficant" and "blobable" artifacts.

* Make emitting IR disjoint to using a container.
Added -emit-ir option.
Simplfiy output.

* Fix typo in options parsing.

* Add a test that ouputs with an emit source map.

* Enable emitting our SlangIR module if no targets are specified.

* Fix issues constructing container.

* Extra checks getting obfuscated source map from a translation unit.

* Fix typo.
