dumbpad refactor - adding support for various PCB revisions (#9259)

* Placeholder commit - Refactored to support different PCB revisions

Individual revision folders still need:
-  info.json
-  readme.md

all v0x folders support up to two LEDs for layer indication

all v1x folders support up to two LEDs for layer indication
plus one extra LED for numlock indication

v0x - supports single-encoder v0.x PCB revisions

v0x_right - supports reversible, single-encoder v0.x PCB revisions

v0x_dualencoder - supports dual-encoder v0.x PCB revisions

v1x - supports single-encoder v1.x PCB revisiions

v1x_right - supports reversible, single-encoder v1.x PCB revisions

* Added info.json and readme.md files for all dumbpad revisions

* More refactoring, adding shared config.h and rules.mk

Removed config.h from default keymap folders - defining TAPPING_TOGGLE in config.h

* Minor formatting fix

* MATRIX_COL_PINS for v1x_right was not reversed - changed to match v0x_right

* adding support for v1x dual encoder PCB

* adding alt-f2 tapdance routine for personal keymaps

* adding dumbpad build using teensy 2.0 instead of Pro Micro

* matched v1x dumbpad encoder and led pins to latest PCB revisions

* updated readme, removed v1x_teensy until someone requests it

* changed device name to match tmk udev rules, removed unnecessary ifdef

* removed user keymaps and folders

* missed hotdox keymap - removing

* fixing info.json keyboard_names for all versions

* Changed biton32 to get_highest_layer in keyboards/dumbpad/v0x/v0x.c

* keyboards/dumbpad/v0x/v0x.c - remove matrix_scan_kb, process_record_kb

* /dumbpad/v0x/keymaps/default/keymap.c - remove empty functions

* /dumbpad/v0x/keymaps/default/keymap.c - changed biton32 to get_highest_layer

* keyboards/dumbpad/v0x_dualencoder/keymaps/default/keymap.c - remove empty functions

* keyboards/dumbpad/v0x_right/readme.md - smaller board layout image

* keyboards/dumbpad/v1x_dualencoder/readme.md - smaller board image

* keyboards/dumbpad/v1x/readme.md - smaller board image

* keyboards/dumbpad/v1x_right/readme.md - smaller board image

* Update keyboards/dumbpad/rules.mk

* Apply suggestions from code review

Batch applying suggestions from review

* fixed removal of led_set_kb

* Implementing requested changes from old pull request 9259

* removing unused rules

* removed rules.mk from dumbpad base folder

* adding templates for each layout

* testing default keymap json

* Testing applying default keymap for dumbpad

* Layout correction: v1.x are 17 position pcb's
