Reduce the number of WrapDirect3D11Texture calls (#20517)

* Reduce the number of WrapDirect3D11Texture calls

Reduce the number of WrapDirect3D11Texture calls by tying the EglSurface lifetime to _renderTexture.
When testing on a 4K display, I observed that eglCreatePbufferFromClientBuffer, which is invoked by WrapDirect3D11Texture, can take around 5 ms per frame.
By reducing the number of eglCreatePbufferFromClientBuffer calls, I was able to improve rendering performance by about 30%.
However, I’m not sure why the previous implementation needed to call WrapDirect3D11Texture on every frame.

* Remove the commented code
