* 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.

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.
