Add an option to preserve symbols and debug_frame.
New strip option named keep_symbols_and_debug_frame, that will keep the
symbols and the .debug_frame. This is meant for use by libc.so only on
arm32. Other libraries might want to use it to keep better unwinding
information on device.
Bug: 132992102
Test: Built libc.so with this option and verified that it contains
Test: the .debug_frame section.
