[modular] ModuleFacetReader for reading a component's module facet

* ModuleFacetReader takes a module URL and returns the
  fuchsia.modular.ModuleManifest the module component declares.

Testing:
* FilesystemForTest used for building a static filesystem (used to build
  a fake directory for component::CmxManifest)
* SysLoaderForTest used to fake out fuchsia.sys.Loader and give dummy
  answers to ModuleFacetReaderImpl.

Peridot

Peridot is a framework for composed, intelligent and distributed user experiences.

Applications not explicitly designed to interoperate (and possibly implemented in different programming languages) are ephemerally downloaded and dynamically composed to run in a shared context. The framework manages application lifecycle, resources and view hierarchy; and well as context and suggestion infrastructure.

State of Peridot experiences is transparently synchronized across user devices using a distributed offline-first storage system.
