SF: Cleanup layer construction

Introduce a LayerCreationArg parameter object, and modify all layer
types to use it rather than having the same set of four arguments.

Along the way simplify all constructors by moving to C++11 style default
values defined in the header, and ensure the destructor is defined in
the implementation file (as a default for most layer types, as only
BufferLayer needs a non-default destructor).

Using a uniform parameter object reduces the amount of work needed to
maintain the upcoming factory interface.

Test: Works on marlin.
Test: atest libsurfaceflinger_unittest
