[Keymap] Added csc027 keymaps for keebio/iris and planck (#7472)

* Added csc027 user folder and keymaps for both keebio/iris and planck

* Moved the git_macros variable out of the process_record_user function.

* Updated the usb_led code to use the new led_update_user instead of the led_set_user function.

* Update users/csc027/defines.h

Removed the "_______" macro definition in defines.h, since it has already been defined in QMK.

* Update users/csc027/defines.h

Removed the "XXXXXXX" macro definition in defines.h, since it has already been defined in QMK.

* Update users/csc027/csc027.c

Simplified several keyboard macro definitions in the csc027.c file by switching from SS_LCTRL to SS_LCTL in their definitions.

* Condensed both the planck and iris rules files to the minimal set of declarations.
