Macro variables usage

Set variables with default value and gcode that does nothing

[gcode_macro CONFIGS]
variable_my_stored_variable: 0
gcode:
  M118 Stored variable as {printer["gcode_macro CONFIGS"].my_stored_variable}

Use those variables in another macro

[gcode_macro PRINT_STORED_VARIABLE]
gcode:
  M118 Value is {printer[gcode_macro CONFIGS"].my_stored_variable}

Change the variables from another macro

[gcode_macro SET_VAR_TO_1]
gcode:
  SET_GCODE_VARIABLE MACRO=CONFIGS VARIABLE=my_stored_variable VALUE=1
  M118 Changed!
