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

* 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

* Update keyboards/dumbpad/v0x/rules.mk

* Update keyboards/dumbpad/v0x/rules.mk

* Update keyboards/dumbpad/v0x_dualencoder/keymaps/default/keymap.c

+
+## Single- vs Dual-Encoder Support
+
+The combined Cherry MX/encoder sockets allow single- and dual-encoder configurations.
+
+The only rule when using two encoders is that there cannot be two encoders on the left side at once, or two on the right side.
+This table shows where the encoders are in the switch grid ("X" for encoder, "s" for switch):
+
+| C0  | C1  | C2  | C3  | C4  |
+|:---:|:---:|:---:|:---:|:---:|
+|     |__X__|  s  |  s  |__X__|
+|     |  s  |  s  |  s  |  s  |
+|     |  s  |  s  |  s  |  s  |
+|__X__|__X__|  s  |  s  |__X__|
+
+- The three encoders in columns C0 and C1 are connected to each other
+- The two encoders in column C4 are connected to each other
+
+So, if doing dual encoders, one must be in column C4 and the other in either C0 or C1. Three or more encoders will not work.
+
+The following sections describe the configurations that the default keymaps in QMK are designed for.
+
+### Single-Encoder (Default Configuration)
+
+In the default configuration, the encoder is in column 0, the bottom left corner below the Pro Micro. All other sockets are filled with switches.
+
+| C0  | C1  | C2  | C3  | C4  |
+|:---:|:---:|:---:|:---:|:---:|
+|     |  s  |  s  |  s  |  s  |
+|     |  s  |  s  |  s  |  s  |
+|     |  s  |  s  |  s  |  s  |
+|__X__|  s  |  s  |  s  |  s  |
+

+
+### Dual-Encoder Bottom
+
+One dual-encoder configuration has encoders in the bottom two corners of the 4x4 grid, and switches in the rest of the grid. The socket in column 0 is left empty.
+
+| C0  | C1  | C2  | C3  | C4  |
+|:---:|:---:|:---:|:---:|:---:|
+|     |  s  |  s  |  s  |  s  |
+|     |  s  |  s  |  s  |  s  |
+|     |  s  |  s  |  s  |  s  |
+|     |__X__|  s  |  s  |__X__|
+

+
+### Dual-Encoder Top
+
+Another dual-encoder configuration has encoders in the top two corners of the 4x4 grid, and switches in the rest of the grid. The socket in column 0 is left empty.
+
+| C0  | C1  | C2  | C3  | C4  |
+|:---:|:---:|:---:|:---:|:---:|
+|     |__X__|  s  |  s  |__X__|
+|     |  s  |  s  |  s  |  s  |
+|     |  s  |  s  |  s  |  s  |
+|     |  s  |  s  |  s  |  s  |
+

+
+### No-Encoder
+
+You may also choose not to use any rotary encoders if you like!
+
+### Bill Of Materials
+
+- Cherry-style mechanical switches
+- EC11 rotary encoder with pushbutton (7-pin) - one or two depending on your desired configuration
+- 1n4148 diodes (thru hole) - one per switch and rotary encoder (if using clickable encoder(s))
+- 1x Arduino Pro Micro or pin-compatible ATmega32u4-based MCU
+- (optional) 3x 3mm LEDs
+- (optional) 3x 330 ohm resistors (for limiting current in LEDs)
+- (optional) 6mm SPST switch for resetting MCU
