LYN-7008 | Focus Mode - Selection unit tests (#4357)

* Refactor existing tests and fixtures, split them up in more granular tests, and add more comments. Signed-off-by: Danilo Aimini <82231674+AMZN-daimini@users.noreply.github.com> * Refactor test fixture for FocusMode to make it more reusable Signed-off-by: Danilo Aimini <82231674+AMZN-daimini@users.noreply.github.com> * Fixture rename, draft of selection test Signed-off-by: Danilo Aimini <82231674+AMZN-daimini@users.noreply.github.com> * Split SetFocus and ClearFocus tests for Editor Focus Mode Signed-off-by: Danilo Aimini <82231674+AMZN-daimini@users.noreply.github.com> * Move BoundsTestComponent to its own file so that it can be reused in Focus Mode Selection tests Signed-off-by: Danilo Aimini <82231674+AMZN-daimini@users.noreply.github.com> * Making progress on selection test. Test compiles now, but selection doesn't seem to be working. Signed-off-by: Danilo Aimini <82231674+AMZN-daimini@users.noreply.github.com> * Removed commented out code from previous iteration. Signed-off-by: Danilo Aimini <82231674+AMZN-daimini@users.noreply.github.com> * Move BoundsTestComponent under the UnitTest namespace Signed-off-by: Danilo Aimini <82231674+AMZN-daimini@users.noreply.github.com> * Viewport selection tests + minor fixes. Signed-off-by: Danilo Aimini <82231674+AMZN-daimini@users.noreply.github.com> * Minor fixes Signed-off-by: Danilo Aimini <82231674+AMZN-daimini@users.noreply.github.com>
