Sort class members to ensure deterministic builds

Class methods and fields are currently sorted at serialization (see
DescriptorSerializer.sort) and at deserialization (see
DeserializedMemberScope.OptimizedImplementation#addMembers). Therefore,
the contents of the generated stub files are sorted in incremental
builds but not in clean builds.

The consequence is that the contents of the generated stub files may not
be consistent across a clean build and an incremental build, making the
build non-deterministic and dependent tasks run unnecessarily (see
KT-40882).

To work around that, this commit sorts class methods and fields when
outputting stub files.

Bug: KT-40882 (there are actually 2 issues in here; this commit fixes
     the first one)
Test: New DeterministicBuildIT + Updated existing test expectation files
