Keyboard: Chimera Ortho refactor (#4652)

* Layout macro refactor

- Renamed KC_KEYMAP to LAYOUT_kc
- Renamed KEYMAP to LAYOUT
- moved LAYOUT above LAYOUT_kc (Hoping this encourages users to use LAYOUT.)
- updated layout macro name in info.json
- white space changes for readability

* Keymap refactor: default

Default keymap now uses `#include QMK_KEYBOARD_H` and LAYOUT macro (from KC_KEYMAP/LAYOUT_kc). Keymap was also refactored to use process_record_user function instead of deprecated action_get_macro from TMK.

Also moved LONGPRESS_DELAY and LAYER_TOGGLE_DELAY definitions to config.h.

* Keymap refactor: dcompact

- Changed chimera_ortho.h include for QMK_KEYBOARD_H
- Updated layout name on keymap layers

* Coding conventions fix in default keymap

* Keymap refactor: gordon

- Changed chimera_ortho.h include for QMK_KEYBOARD_H
- Removed redundant includes of action_layer.h and process_tap_dance.h (superseded by QMK_KEYBOARD_H)
- Removed redundant definitions for KC_NO and KC_TRNS
- Updated layout name on keymap layers

Refactor quantum/split_common/i2c.c, quantum/split_common/serial.c (#4522)

* add temporary compile test shell script

* Extended support of SKIP_VERSION to make invariant compile results during testing.

* build_keyboard.mk, tmk_core/rules.mk: add LIB_SRC, QUANTUM_LIB_SRC support

Support compiled object enclosed in library.

e.g.
```
LIB_SRC += xxxx.c
xxxx.c --> xxxx.o ---> xxxx.a
```

* remove 'ifdef/ifndef USE_I2C' from quantum/split_common/{i2c|serial}.c

* add SKIP_DEBUG_INFO into tmk_core/rules.mk

When SKIP_DEBUG_INFO=yes is specified, do not use the -g option at compile time.

* tmk_core/rules.mk: Library object need -fno-lto

* add SKIP_DEBUG_INFO=yes

* remove temporary compile test shell script

* add '#define SOFT_SERIAL_PIN D0' to keyboards/lets_split/rev?/config.h

* quantum/split_common/serial.c: Changed not to use USE_I2C.
