Introduce MetadataSource as a way to store the original descriptor for
any element (before any lowerings) and maintain it until the end of the
codegen where it's used in generating the metadata. Note that JVM
signatures written to the metadata are formed from the _resulting_
generated elements, not by mapping the original descriptors.
Some corner cases are not supported yet, namely properties declared in
companion objects, synthetic methods for property annotations,
JvmPackageName, etc.

The only client of this data is reflection, and since anonymous objects
do not have constructors in the source code, they shouldn't in
reflection as well
#KT-20442 Fixed
The change in DescriptorSerializer is needed so that serialized protos
of enum entry classes which are resolved in sources
(LazyClassDescriptor) and are deserialized from binaries
(EnumEntrySyntheticClassDescriptor) are the same. There are tests on
incremental compilation in JS that check that the serialized proto is
exactly the same after rebuild and after an incremental build.
#KT-22048 Fixed
This patch mutes the following test categories:
* Tests with java dependencies (System class,
java stdlib, jvm-oriented annotations etc).
* Coroutines tests.
* Reflection tests.
* Tests with an inheritance from the standard
collections.
