EEVEE-Next: Mixed resolution with orthographic projection

Browse Source 
When using mixed resolution rendering with an orthographic projection
the display was not correct. The reason was that the view boundaries
were decomposed from the winmat correctly, but when re-composing
the matrix it assumed to be in perspective.

This is fixed by composing an orthographic winmat when it was sourced
from a orthographic winmat.

Fixes #119514
