cmake: xtensa: use absolute paths for tools

CMake has convention of changing relative paths to absolute
for CMAKE_* variables. It does it automatically f.e. CMAKE_C_COMPILER.
However for our tools like objcopy we have to do it manually.
It also helps with integration of CMake in some IDEs.

CHT & BYT have limited amount of IRAM so are sensitive to selection of
built in audio components. Disable KBP by default, but this could be
enabled if other components were disabled.
