[NUCLEOs] enhance I2C API to make it work with EEPROM
[NUCLEO_L053R8] Fix ticker issue
Added support for cpputest library. UT libray now compiles as separate lib, just like other libs. For example ETH or RTX. Added support for cpputest sources in root of mbed project (on the same level with mbed sdk repo). changes include adding new paths to the project. Two example UT (UT_1, UT_2 are added). New option -O is introduced to force 'test build only'
[NUCLEO_L053R8] Remove call to SystemClockUpdate function.

It's ok to remove this call on this target because the same system clock
frequency is used with HSE and HSI clocks.
