build: add ENABLE_ALL option
build: add ENABLE_ALL option

-DENABLE_ALL will enable all the dependencies and features unless user did not
explicitly switched some of them OFF, i.e. configuring in the following way
is possible:
  cmake -DENABLE_ALL=ON -DENABLE_TEXTLOG=OFF
and it will configure all targets except samples.

TODO: As of now ENABLE_ALL is not fully implemented, it will not affect all
  of the ENABLE_* options. Those options it don't affect are placed above
  ENABLE_ALL definition and require some rework and/or pending CI adoption.
