[Compose] Setup the nav graph and navigation logic

[luongvo]

Why

Our current Android template for Jetpack Compose is too inceptive to start a new project. To make our Compose template truly designed for Jetpack Compose and follow the right principles, we need to work on various updates to the project structure.

In this task, we will set up the nav graph and navigation logic in Jetpack Compose. This follows what we have achieved in:

• Jetpack Compose Crypto showcase (this PR).
• Knowledge sharing session about Navigation in Jetpack Compose.

Who Benefits?
