Update readme.md files, update architecture diagram

[Patrik-Stas]

• The root readme.md is more general and also
  • it puts aries-vcx along with the smaller subcrates as main components
  • libvcx is nuanced as "one of the crates built on aries-vcx"
• Add specific readme for libvcx
• Add specific readme for aries-vcx
• Updated maintainers file
• Update architecture diagrams - where originally we had 1 diagram which spanned from libcx wrappers all way down to aries-vcx modules, now there's 2 diagrams instead.
  • One diagram for aries-vcx crate architecture only
  • One diagram for libvcx and surrounding language wrappers, depicting aries-vcx simply as 1 component
