While it is invalid to mix //visibility:public with other rules in the
visibility property in a .bp file tt was possible, by overriding
defaults, to have //visibility:public mixed in with other rules in the
effective visibility rules. That caused problems when those effective
rules were used in an sdk snapshot.
This change replaces any set of rules that include //visibility:public
with just the //visibility:public rule. That simplifies those rules,
making them cheaper to process and ensures that the effective rules are
valid in the visibility property.
Adding test support required some refactoring of the
effectiveVisibilityRules(BaseModuleContext, ...) and underlying methods
to take a Config instead of BaseModuleContext as the tests do not have
access to BaseModuleContext.

Add dex2oat to art-module-host-exports, build it and check the
generated Android.bp file in the snapshot to ensure the
visibility property for the dex2oat prebuilt does not mix
//visibility:public with other rules.

When both prebuilt and source versions of a module are present in the
build an implicit dependency is added from source -> prebuilt. This
change excludes that dependency from visibility enforcement as it
provides no value and would otherwise require an sdk snapshot to
rewrite the visibility of the generated prebuilt modules which would
be complicated.
The rewriting would include:
* Detecting //visibility:public and just passing that straight through.
* Detecting //visibility:private and replacing that with the location
of the source.
* Otherwise, adding the location of the source to the visibility
property.
This adds a general mechanism to allow any dependency to be excluded
from visibility enforcement by simply using a tag that implements
the ExcludeFromVisibilityEnforcementTag interface.

The filesystem object was available through ModuleContext.Fs(), but
gives too much access to the filesystem without enforicing correct
dependencies. In order to support sandboxing the soong_build
process move the filesystem into the Config. The next change will
make it private.

Exports visibility and package mutator registration functions so they
can be used in sdk testing. Updates sdk test to support visibility and
package modules.
Adds EffectiveVisibility(...)[]string function to make the effective
visibility rules available to sdk snapshot creation.
Extracts compositeRule.Strings() []string from compositeRule.String()
method so that it can be used by above func.
Adds visibility property to sdk snapshot and prebuilt modules along
with a test to ensure it works properly.
Adds dir parameter to CheckSnapshot so that it can check the snapshot
generated for a non-root package. That is required in order to ensure
that visibility of :__subpackages__ on a source module in package
<pkg> is resolved to an effective visibility of
//<pkg>:__subpackages__ on its corresponding prebuilt.

However only allow it when they are merged from different defaults.
Extend the tests to cover that and other cases with visibilities in
defaults.
Also avoid dumping the whole visibility spec in the error message when a
visibility check fails, because it gets noisy for long visibility lists, and
can be confusing when //visibility:public gets merged with other visibility
rules.

Implementation uploaded for review. Includes unit tests but does not

more general issues with prebuilts and namespaces is resolved.
