Refactor/types namings tsdoc redundant code

[VGabriel45]

This PR introduces the following changes:

• refactor "permissions" to refer to Session Permissions
• refactor "session" to refer to Session (implicit or explicit)
• refactor "explicitSession" to refer to explicit session
• improved RequestActionType types to cover more explicit scenarios
• added "getAllImplicitSessions()" and getAllExplicitSessions()"
• refactor "permissions" type in wallet/primitives SessionPermissions to be Permission[], [Permission, Permission[]] was causing too many type issues on client side and required to be casted

sessionAddress is an argument for addExplicitSession but its also a property of the explicitSession.

[corbanbrook]

This typing [Permission, ...Permission[]] is cute typing trick that uses a tuple type to specify that there must be at least 1 permission given in the array. where as Permission[] allows an empty array. Was this change intended?

[VGabriel45]

The problem I noticed with this sugar is that you need to cast "permissions" to [Permission, ...Permission[]] all the time otherwise typescript will complain, this looks like a workaround and is not very intuitive for the developer that is integrating, I would prefer if the sdk simply checks the permissions array to see if it's empty or not.

[corbanbrook]

This is strange to me ... we are tagging the event listener with a chain id?

[VGabriel45]

Yes, exactly. We're adding a chainId property to the listener function itself because the DappClient needs it, so it's an ExplicitSessionEventListener with an extra property "chainId" which makes the DappClientExplicitSessionEventListener.

Im not sure why the ImplicitSession type is omitting isImplicit. It might be better to use a discriminating type union here.

[corbanbrook]

Specifically if you had something like:

type Session = ImplicitSession | ExplicitSession

interface ImplicitSession  {
  type: 'implicit',
  ...
}

interface ExplicitSession  {
  type: 'explicit',
   ...
}

These could extend a base interface with common properties.

[VGabriel45]

Yep agree, I refactored this one.

[corbanbrook]

Looking good. just a couple questions about the Session, ExplicitSession, ImplicitSession typings. and a couple other small things.
