Setup debugging based on nvim-dap-view

[Kailian-Jacy]

Reason

• Extensible. Providing out-of-box APIs.
• Simple.
• Providing necessary facilities like view and terminal.

Existing problems

• Frame jumping is not working.
• Terminal does not show up.

Problem

Lacking conditional breakpoints.

-> Could be worked around with REPL.

Bug: tab switching keymap not applied

When opening nvim-dap-views, when getting to the console page:

• title blinks and eliminate.
• keymaps not applied. Pressing "R" would restart the program: caused by lazy loading.

[Kailian-Jacy]

Problem: Could not automatically close nvim-dap window
