Previously, Configurable.Get() copied the value in the property,
because it needed to return a pointer in order to indicate whether
the property was set or not. Now, it returns a ConfigurableOptional[T],
which is the same as the pointer, but it prevents users from altering
the pointed-to value, so we don't need to copy it.
There are still copies for slice properties, because those are also
pointers. In the future we may want to consider making an ImmutableList
type to use instead.

Preivously it attempted to print all conditions and their values,
but that doesn't tell you which one was wrong, and the formatting was
all weird due to trying to print complex go types.

* changes:
Don't sort the results of TransitionMutator.Split
Apply outgoing transitions when adding dependencies
Delete transition variation when no matching variant was found
The ordering of variants can be significant when adding
inter-variant dependencies, as a variant can only depend on earlier
variants. Allow maintaining the existing variant ordering when
converting mutators to TransitionMutator by keeping the ordering
of TransitionMutator.Split. Variations that were requested by
incoming dependencies that are not present in Split are still
sorted, as they have no inherent ordering.

TransitionMutators can always return "" from OutgoingVariation in
order to implement the equivalent of CreateLocalVariations - a
variation that doesn't affect which variation of dependencies is
selected. The same need applies when creating the dependency after
the TransitionMutator. Call OutgoingVariation on the parent module
when adding new dependencies unless the variation was explicitly
requested.

TransitionMutators sometimes apply to one variant of a module but
not to another. Deleting the variation when all variants were
untouched is insufficient if a post-mutator dependency is being added
on a variant that was untouched. Delete the variation whenever
no matching incoming variant was found.

ReplaceDependencies[If] currently replaces dependencies on a given
module with the current module. It expects to find a variant of the
given module that has the exact same variations as the current module.
That was sometimes handled via aliases, but TransitionMutators don't
support aliases, they use IncomingTransition to rewrite the variation
instead.
In all current usages of ReplaceDependencies[If], the given module
is also a direct dependency of the current module. Instead of looking
for the exact same variations, look for the variant that is a dependency
of the current module.

When adding a dependency on a module that has already had variants
created by a TransitionMutator, ignore any variation added by the
TransitionMutator to the current module if the TransitionMutator
didn't apply to the target module. This requires passing in the
list of variations requested by the AddVariationDependencies call
so that explicitly requested variations are not ignored.
This fixes TestAndroidTest_FixTestConfig when the override mutator
is converted to a TransitionMutator, as it can't add a dependency from
the "foo_test" module with an empty override variation to the
"foo" module that has no override variation.

TransitionMutator's top down mutator is suffixed with _deps, but
that name is often used by other mutators related to the
TransitionMutator, causing unexpected conflicts. Use _propagate
instead.

In order to do less cloning, refactor selects so that all the
soong-visibile structs are immutable to soong and can be reused.
Additionally, refactor how the inner linked list of selects is managed,
so that the append/prepend/replace logic is simpler.

The biggest issue here is that Configurable objects needed to be
cloned before appended to one another, otherwise some Configurables
that were used in defaults could be edited after being applied to one
module and apply a different value to another module.
Also fix an issue where a select without a defined appendWrapper
always evaluated to nil.
I plan to make a followup refactor cl to make these things clearer,
but start with the bugfix.

Sometimes modules add arch-variant properties in load hooks, to disable
modules by default on certain platforms for example. When changing the
property to a Configurable property, these load hooks would also need
to be changed in order to have a matching type for
ExtendMatchingProperties.
Since this can be kindof a pain to address everywhere, for now,
special case the extension functions to promote non-configurable
properties to configurable ones. We can remove this later when
everything switches to configurable properties.
