This name makes more sense and one api does the job of two.
We never needed two apis at first place though.
Mark left/right_size_set as legacy apis too.
This patch also implements min_split_ratio on parts.
@feature
refer T5359
This allows user to set size hints to be respected and
request panes to ignore combined min size.
If this flag is set, the minimum size set by efl_gfx_size_hint_min_set()
is respected forcefully.
