We are going to deprecate `WITH_RUNTIME` directive. The main reason
behind this change is that `WITH_STDLIB` directive better describes
its meaning, specifically it will add kotlin stdlib to test's classpath.
When copying top level declarations from multifile parts to facades,
also copy corresponding properties. This allows to keep their
annotations, which are later used in codegen (for example, to generate
ACC_DEPRECATED on property accessors), and allows to get rid of the hack
where the JVM name of the property accessor was computed prematurely via
methodSignatureMapper.
Also, don't copy `$annotations` methods for non-const properties to
facades because the old backend only generates them in parts (which
might be a separate problem, see KT-27644).
#KT-40262 Fixed
Do not change origin of multifile class bridges to something else
because, as it turns out, there are numerous origin-specific checks in
the codegen that start to behave differently for multifile bridges.
Instead of the method-targeted origin MULTIFILE_BRIDGE, use new class
origin JVM_MULTIFILE_CLASS to detect whether a declaration is a
multifile bridge.

The change is a bit complicated because the name mapping logic is
refactored so that we would compute the needed suffix first (either
module name, or multifile part class name), and then shove it into the
mangled name between the original function name and "$default", if the
function in question is the default arguments adapter.
The main motivation for this change was to fix KT-41809, but as a side
effect, private functions with default arguments in multifile parts now
also contain the file name, just like normal private functions.
