Drop the minimal variant of the default port implementation (#4331) 
The minimal variant became quite meaningless lately. There were two
port APIs originally that had extra functions in the default port
in addition to the core-mandated implementations: the I/O and
Termination port APIs. However, the extra Termination API code was
removed a year ago, leaving some minimal extension in the I/O port
only. As the overhead of the extension is negligible, it is not
worth maintaining two library variants.

Therefore
- this commit removes the minimal variant of the default port lib,
- rewrites uses of the minimal variant to use the variant with the
  I/O extension, and
- updates targets where I/O port code was copy-n-pasted.

README.md

This is a port for espressif's esp-idf (esp32). The LIBM, LTO and STRIP options should be disabled, so to build under the IDF toolchain, just run the following command

python tools\build.py --toolchain=cmake/toolchain-esp32.cmake --cmake-param "-GUnix Makefiles" --jerry-cmdline=OFF --jerry-port-default=OFF --jerry-libm=OFF --lto=OFF --strip=OFF

NB: the LIBM, STRIP and LTO might be disabled by platform as well. I strongly suggest limiting heap memorry with '--mem-heap=128' but that really depends on the SRAM avaiulable on your esp32.

Then copy the artefacts 'build/lib/*.a' in an esp-idf component named 'jerryscript' (eg) and use a 'CMakeLists.txt' like this one

# assumes there is a component with this the following 
# - set the JERRY_DIR wherever the jerryscript source code (the include files) is
# - a "lib" directory with the 2 libraries below

set(JERRY_DIR ${PROJECT_DIR}/../../jerryscript/)
