Make string optimization (#179)

* Add NO_STL std::reverse implementation (#174)

Follows the example implementation on [1].

[1] https://en.cppreference.com/w/cpp/algorithm/reverse

* Merge remote-tracking branch 'origin/feature/no_stl_unit_tests' into development

# Conflicts:
#	include/etl/stl/alternate/algorithm.h
#	include/etl/stl/alternate/iterator.h
#	include/etl/version.h
#	library.json
#	library.properties
#	support/Release notes.txt
#	test/test_no_stl_algorithm.cpp
#	test/test_no_stl_iterator.cpp
#	test/vs2017/etl.vcxproj

* Fix merge function duplication

* Merge remote-tracking branch 'origin/development'

# Conflicts:
#	include/etl/private/choose_pair_types.h
#	include/etl/private/choose_tag_types.h
#	include/etl/version.h
#	library.json
#	library.properties
#	support/Release notes.txt

* Update README.md

* make_string optimisation. String length is calculated in compile time, no need to use strlen.
