Mark null project initial screen as zoom-initialized The variable `m_Initialized` in `BASE_SCREEN` is used by `SCH_EDIT_FRAME` to mark whether a screen had its zoom level initialized by the "zoom to fit screen" action. When this variable is `false`, the function `SCH_EDIT_FRAME::DisplayCurrentSheet()` performs "zoom to fit screen", modifying the zoom level. This function is indirectly called in the undo routines, so if `m_Initialized` is not set to `true`, a zoom change will occur when the user undoes an operation, a behavior that is undesired. `m_Initialized` was not initialized to `true` for the null schematic (the schematic that is loaded if no project is loaded), causing the aforementioned undesired behavior. To prevent this, I've changed the `SCH_EDIT_FRAME` constructor to set `m_Initialized` to `true`, since it zooms to fit screen already. I've moved `m_Initialized` from `BASE_SCREEN` to `SCH_SCREEN`, as it is used only in Eeschema, and renamed it to `m_zoomInitialized`, a name I believe that better describes what this variable does. I've also introduced the function `SCH_EDIT_FRAME::initScreenZoom()` to group the "zoom to fit screen" action with setting `m_Initialized` to `true`, as they often should occur together. I'd also like to say that I'm not confident whether `SCH_EDIT_FRAME::DisplayCurrentSheet()` should perform the zoom level initialization at this point, but I have decided to not change this behavior for now, as the commit history suggests it's several years old. Fixes https://gitlab.com/kicad/code/kicad/issues/7343
