Disable libjerry-math by default (#4428)

Browse Source 
Normally, it is more usual and safe to use a toolchain's native
math library. Especially, if multiple components of a project use
math functions, in which case all components should be linked
against the same libm.

The libjerry-math can be used, of course, but as it needs extra
care and consideration, it should be opt-in.

This is a port for espressif's esp-idf (esp32). The MATH, 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-math=OFF --lto=OFF --strip=OFF
python tools\build.py --toolchain=cmake/toolchain-esp32.cmake --cmake-param "-GUnix Makefiles" --jerry-cmdline=OFF --jerry-port-default=OFF --lto=OFF --strip=OFF
```
NB: the MATH, 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.
