[Feature] | Re-organize modules

[hrodrick]

Which kind of problem this feature would address? Please describe.
Currently the modules of the project are a bit disorganized.

Describe the solution you'd like
Organize the modules following this structure:

buildSrc
flowforms-core
 - android
 - common
 - iOS
 - etc
example
  - shared
  - ios-example (uses shared)
  - android-example (using shared ViewModel, so please also remove current ViewModels in android example)
      - activity
      - fragment
      - compose

Additional context
This will make the library easier to maintain, extend and understand.
