G-API: Introduce new `reshape()` API (#12990) * Moved initFluidUnits, initLineConsumption, calcLatency, calcSkew to separate functions * Added Fluid::View::allocate method (moved allocation logic from constructor) * Changed util::zip to util::indexed, utilized collectInputMeta in GFluidExecutable constructor * Added makeReshape method to FluidExecutable * Removed m_outputRoi from GFluidExecutable * Added reshape feature * Added switch of resize mapper if agent ratio was changed * Added more TODOs and renamed a function * G-API reshape(): add missing `override` specifiers Fix warnings on all platforms
