Consolidate Binepad BN009 R1 and R2 into common folder

[vinorodrigues]

Description

This PR is intended for the develop branch as it's deemed a breaking change (insofar as moving folders).

This PR consolidates the Binepad BN009 R1 (ft. a ATMega32U4 mcu) and R2 (ft. the PCB upgrade to the STM32F103 mcu) into a single folder. The two keypads feature the same VID/PID, same matrix grid, and same keymap.

Further cleanup has been performed on the original KB, keyboards/binepad/bn009, now moved to the keyboards/binepad/bn009/r1 folder:

• config.h and rules.mk settings moved to info.json to enable data-driven compile.
• default and via kemaps moved to keymap.json for data-driven keymaps.

Folder items in keyboards/binepad/bn009r2 have been moved to keyboards/binepad/bn009/r2 and common items merged in.
