MakotoKurauchi 881f27b461 [Keyboard] Cleanup helix rules options ()
* add temporary test shell-spript

* Use LINK_TIME_OPTIMIZATION_ENABLE instead of Link_Time_Optimization

No change in build result.

* Helix config.h use '#pragma once'

No change in build result.

* Helix helix.h,rev?/rev?.h,pico/pico.h use '#pragma once'

No change in build result.

* Use drivers/avr/pro_micro.h instead of keyboards/helix/pro_micro.h

No change in build result.

* remove keyboards/helix/{rev2|pico}/serial_config.h

No change in build result.

* 'HELIX_ROWS' macro is now referenced only in rev1/config.h and rev2/config.h.

No change in build result.

* The contents of helix/rules.mk were distributed to subdirectories.

This is a preparation to create a new subdirectory for helix code using split_common.

No change in build result.

remove 'USE_I2C = yes', 'SUBPROJECT_rev1 = no' from keyboards/helix/rules.mk.
follow code move from keyboards/helix/rules.mk to keyboards/helix/{rev1,rev2,pico}/rules.mk.

----
 SRC += i2c.c
 SRC += serial.c
 SRC += ssd1306.c

 CUSTOM_MATRIX = yes
---

* helix/{i2c.[ch], serial.[ch], ssd1306.[ch]} move into helix/local_drivers/

No change in build result.

* Simplified 'helix/pico/keymap/*/rules.mk' using KEYBOARD_LOCAL_FEATURES_MK.

No change in build result.

 * add keyboards/helix/pico/local_features.mk
 * add 'KEYBOARD_LOCAL_FEATURES_MK := $(dir $(lastword $(MAKEFILE_LIST)))local_features.mk' into keyboards/helix/pico/rules.mk
 * remove HELIX_CUSTOMISE_MSG from keyboards/helix/pico/keymaps/*/rules.mk
 * remove HELIX= process from keyboards/helix/pico/keymaps/*/rules.mk
 * remove convert code(helix to standaerd) from keyboards/helix/pico/keymaps/*/rules.mk
 * add 'include $(strip $(KEYBOARD_LOCAL_FEATURES_MK))' into keyboards/helix/pico/keymaps/*/rules.mk

* Simplified 'helix/rev2/keymap/*/rules.mk' using KEYBOARD_LOCAL_FEATURES_MK.

No change in build result.

* add keyboards/helix/rev2/local_features.mk
* add 'KEYBOARD_LOCAL_FEATURES_MK := $(dir $(lastword $(MAKEFILE_LIST)))local_features.mk' into keyboards/helix/rev2/rules.mk
* remove HELIX_CUSTOMISE_MSG from keyboards/helix/rev2/keymaps/*/rules.mk
* remove HELIX= process from keyboards/helix/rev2/keymaps/*/rules.mk
* remove convert code(helix to standaerd) from keyboards/helix/rev2/keymaps/*/rules.mk
* add 'include $(strip $(KEYBOARD_LOCAL_FEATURES_MK))' into keyboards/helix/rev2/keymaps/*/rules.mk

* Added helix keyboard build NEW method.

* test end remove test script. Revert "add temporary test shell-spript"

This reverts commit ec49f63b2dc0f2b3fe8c1c36ffa615cee2f7e3ed.

* Extended the 'HELIX=' option. add keyword 'verbose', 'no_ani'.

No change in build result.

* update keyboards/helix/{rev2,pico}/keymaps/default/readme.md

* rename KEYBOARD_TOP_DIR to HELIX_TOP_DIR in rules.mk

* update keyboards/helix/{rev2,pico}/keymaps/default/readme_jp.md

* rm keyboards/helix/pico/oled/rules.mk

* update helix's readmes. All the ':avrdude' was replaced with ':flash'.
