build system: Split setting of compiler optimisation level from assertions on/off

build system: add menuconfig choice for optimization level, reorganize C*FLAGS This change adds two options (Debug/Release) for optimization level. Debug enables -O0, release enables -Os and adds -DNDEBUG (which removes all assert() statements). Debugging symbols are kept in both cases, although we may add an option to strip output file if necessary. Also we used to define all common compiler flags in CPPFLAGS, and then appended them to CFLAGS/CXXFLAGS. It makes it impossible to add preprocessor macros to CPPFLAGS at component level (one has to use CFLAGS/CXXFLAGS instead). Some third party libraries are not compatible with this approach. Changed to the more common way of using these variables.

This option sets compiler optimization level (gcc -O argument).
- for "Release" setting, -Os flag is added to CFLAGS.

"Release" with -Os produces smaller & faster compiled code but it
may be harder to correlated code addresses to source files when debugging.
To add custom optimization settings, set CFLAGS and/or CPPFLAGS
in project makefile, before including $(IDF_PATH)/make/project.mk. Note that
custom optimization levels may be unsupported.
