Mismatch on getting wide angle intra mode between text and VTM

Description

In spec text D7 vE, wide angle intra mode mapping is specified in 8.4.5.2.6 where CbW and CbH are used if the luma CU mode is ISP.

However, in VTM7.1, there are two different functions dealing with it. One is IntraPrediction::getWideAngle() which is correct and the other is PU::getWideAngIntraMode() which is wrong.
Function PU::getWideAngIntraMode() always uses TuWidth and TuHeight even if the CU is ISP.

Suggest to fix function PU::getWideAngIntraMode() and align with the text.
