[Keyboard] Cleanup helix rules options (#6952)
* 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
---

This reverts commit 5dac20cd0f8b4bc192edb2313652c1635f829657.
* 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'.
* remove F_CPU, ARCH, F_USB, INTERRUPT_CONTROL_ENDPOINT from helix/rules.mk
