Bank tabs with proper insertion

What has been done?

Implemented the tab functionality of the [Bank] interface to include the tabs list at the top, as well as the empty space components of each tab's last row. Additionally, modifications to the insertion mode were made to account for tab of the already implemented

Proposed Changes

• Added BankTabs.kt object which provides utility functions for dropping [Items] into tabs
• Added bank_tabs.plugin.kts for handling the unregistered on_component_to_component_item_swap
• Removed erroneous references in Bank.kt to tabs and varbits
• Modified bank.plugin.kts on_component_to_component_item_swap for the [Bank.BANK_MAINTAB_COMPONENT] item to item drops in order to accommodate the tabs list component functionality, as well as the insertion mode portions to support tabs and updating varbits accordingly

This is a good base, but has tons of bugs. Also cannot collapse tabs. Thanks for saving me some time though!
