feat(config): add USE_PCF8563 build switch to run without the RTC chip

Browse Source 
Some PCB variants may not populate the PCF8563. Guards RTC init/read
in HomeApp_OnStart(), the WriteDateTime() save in SetClockApp, and the
I2C/RTC diagnostic scans in Self_Test() behind #if USE_PCF8563. When
disabled, the firmware runs entirely on the Timer1-driven software
clock; date/time just won't survive a power cycle without the chip.
