[Bug] Fix Login Screen Buttons can be Pressed While Animating

[ChrisLolz]

What are the changes the user will see?

• When pressing the enter key or clicking the login screen buttons rapidly, the outside buttons will no longer go upwards.
• The login buttons will only work when the screen has finished animating
• Prevents closing the rename Pokemon screen while the UI is still moving.

Why am I making these changes?

Mainly to fix #5163

What are the changes from a developer perspective?

• Added to check to see if the container still has tweens remaining in the action listeners of FormModalUiHandler, LoginFormUiHandler, ModalUiHandler, and RegistrationFormUiHandler.
• Moved the creation of infoContainer into its own function to make setup more clean since ExternalPartyContainer is created on its own function already.

Screenshots/Videos

You can't really tell but I am spamming enter and clicking in these videos

How to test the changes?

I'm unable to host my own local server so I just changed line 30 and 31 to true of login-phase.ts to force the login screen. Otherwise just test manually by clicking the buttons.
