Remove build option firmware size impacts (#6947)

* Update rules.mk template to remove build option size impacts

* Add rules.mk cleaning script

* Update all rules.mk files to remove build option firmware size impact messages

* Remove references to feature filesize in documentation

* Revert "Update all rules.mk files to remove build option firmware size impact messages"

This reverts commit 7cfe70976bcc223bf47c960b2e6af8596df80a32.

* Fix regex in cleanup script and exclude keymaps/ directories

* Update quantum/template/avr/rules.mk

Fixed missing tabs/spaces.

 * `NO_USB_STARTUP_CHECK`

 * `LINK_TIME_OPTIMIZATION_ENABLE`
-  = Enables Link Time Optimization (`LTO`) when compiling the keyboard.  This makes the process take longer, but can significantly reduce the compiled size (and since the firmware is small, the added time is not noticable).  However, this will automatically disable the old Macros and Functions features automatically, as these break when `LTO` is enabled.  It does this by automatically defining `NO_ACTION_MACRO` and `NO_ACTION_FUNCTION`

 To initialize your display, call `lcd_init()` with one of these parameters:
 ````
 LCD_DISP_OFF             : display off
 LCD_DISP_ON              : display on, cursor off
 LCD_DISP_ON_CURSOR       : display on, cursor on
-LCD_DISP_ON_CURSOR_BLINK : display on, cursor on flashing 
+LCD_DISP_ON_CURSOR_BLINK : display on, cursor on flashing
 ````
 This is best done in your keyboards `matrix_init_kb` or your keymaps `matrix_init_user`.  
 It is advised to clear the display before use.
