If we're moving the cursor up, its vertical movement should be stopped
at the top margin. It should not magically jump up to the bottom margin.
Similarly, this applies to moving down and the bottom margin.
Furthermore, this constraint should always apply, not just when the
start position is within BOTH margins

Fixes #2929.

- Fix snapping to the cursor in "Terminal Scrolling" mode (GH-2705)

fixes GH-1222

  PSReadline calls SetConsoleCursorPosition on each character. We try to snap.

  However, we'd only ever do this with the visible viewport, the viewport
  defined by `SCREEN_INFORMATION::_viewport`. When there's a virtual viewport in
  Terminal Scrolling mode, we actually need to snap the virtual viewport, so
  that this behavior looks more regular.

- make filling chars (and, thus, erase line/char) unset wrap (GH-2831)

EraseInLine calls `FillConsoleOutputCharacterW()`. In filling the row with
chars, we were setting the wrap flag. We need to specifically not do this on
ANY _FILL_ operation. Now a fill operation UNSETS the wrap flag if we fill to
the end of the line.

Originally, we had a boolean `setWrap` that would mean...
- **true**: if writing to the end of the row, SET the wrap value to true
- **false**: if writing to the end of the row, DON'T CHANGE the wrap value

,- current wrap value
| ,- fill last cell?
| | ,- new wrap value
| | | ,- comments
|-|-|-|
|1|0|0| THIS CASE WAS UNHANDLED

To handle that special case (1-0-0), we need to UNSET the wrap. So now, we have
~setWrap~ `wrap` mean the following:
- **true**: if writing to the end of the row, SET the wrap value to TRUE
- **false**: if writing to the end of the row, SET the wrap value to FALSE
- **nullopt**: leave the wrap value as it is

- do not allow CUU and CUD to move "across" margins. (GH-2996)

If we're moving the cursor up, its vertical movement should be stopped

Similarly, this applies to moving down and the bottom margin.

- Return to ground when we flush the last char (GH-2823)

The InputStateMachineEngine was incorrectly not returning to the ground
state after flushing the last sequence. That means that something like
alt+backspace would leave us in the Escape state, not the ground state.
This makes sure we return to ground.

Additionally removes the "Parser.UnitTests-common.vcxproj" file, which
was originally used for a theoretical time when we only open-sourced the
parser. It's unnecessary now, and we can get rid of it.

Also includes a small patch to bcz.cmd, to make sure bx works with
projects with a space in their name.
