Frantisek Hrbata 1c92945f59 change(examples): switch examples to use a minimal build

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.

Example: General Purpose Timer

This example illustrates how to use gptimer APIs to generate periodic alarm events and how different alarm actions behave on events.

How to Use Example

Hardware Required

A development board with ESP SOC chip
A USB cable for Power supply and programming

Build and Flash

Run idf.py -p PORT flash monitor to build, flash and monitor the project.

(To exit the serial monitor, type Ctrl-].)

See the ESP-IDF Getting Started Guide for all the steps to configure and use the ESP-IDF to build projects.
