Currently, several example dependencies rely on the fact that all
registered components are added to the build, along with components
specified in common requirements. This results in longer build times
because even unused components must be built. Switch all examples to use
idf_minimal_build to compile only the components actually required by
the example.

LP core was unable to boot when system was in deepsleep.
This was due to lp uart init in LP rom using XTAL as clk source,
which is normally powered down during sleep.
This would cause lp uart to get stuck while printing ROM output,
and the app would never boot.
Also fixed wrong wakeup cause used by HP core for ULP wake up
When using USB-serial-jtag for monitoring idf-monitor will lose connection
during deep sleep (because the peripheral powers down) and will need
some time to reconnect when we wake-up. In the ULP examples this would result in
the chip waking up->printing-> going back to sleep, before idf-monitor is even able
to connect, and users would erroneously assume the chip never woke up.
Add a 1 sec delay at the start of the examples to improve the user experience when
using jtag-serial.
