change: remove STUB_LOG_ENABLE macro from the library usage

[erhankur]

Description

1. The STUB_LOG_ENABLE macro will be enabled from the application and will not be used in the library. Unused functions will not be included in the final binary, so this is okay.
2. stub_lib_log_printf is implemented in a simple way to avoid using ets_vprintf, which is not defined in the ROM on many targets. Instead of re-implementing it, a simpler approach was chosen.
3. esp_rom_caps.h files are added for the future use.
4. Library cmake target names can be configured from the application. This is required by the OpenOCD stub when compiling command-based targets. This approach will also help to pass different compile definitions for each command.
