Fixes #3947 Adds Fake driver and fixes fluent tests (iteration-zero) (#4225)

* Consider width2 chars that are not IsBmp

* Apply same fix in WindowsDriver

* Explicitly use type of local variable

* Revert changes to WindowsDriver

* Assume we are running in a terminal that supports true color by default unless user explicitly forces 16

* Switch to SetAttribute and WriteConsole instead of WriteConsoleOutput for 16 color mode

* Fix some cursor issues (WIP)

* Remove concept of 'dirty rows' from v2 as its never actually used

* Remove damageRegion as it does nothing

* Make string builder to console writing simpler

* Radically simplify Write method

* Simplify conditional logic

* Simplify restoring cursor position

* Reference local variable for console buffer

* Reduce calls to ConsoleWrite by accumulating till attribute changes

* Fixes for VTS enabled

* Fix _lastSize never being assigned

* Fixes VTS for Force16Colors

* Fixes force16Colors in VTS

* Fixes escape sequences always echoing in non-VTS

* Force Force16Colors in non-VTS. It have a bug in adding a newline in the last line

* Abstract away how we change attribute

* WIP - Make WindowsOutput use base class

* WIP working to fix set cursor position

* Remove commented out code

* Fixes legacy output mode

* Fixes size with no alt buffer supported on VTS and size restore after maximized.

* Fix set cursor which also fixes the broken surrogate pairs

* Add force parameter

* Fixes an issue that only happens with Windows Terminal when paste surrogate pairs by press Ctrl+V

* In Windows escape sequences must be sent during the lifetime of the console which is created in input handle

* Ensure flush the input buffer before reset the console

* Flush input buffer before reset console in v2win

* Fixes issue in v2net not being refreshing the menu bar at start

* Only force layout and draw on size changed.

* Fix v2net issue not draw first line by forcing set cursor position

* Set _lastCursorPosition nullable and remove bool force from set cursor position

* Remove force parameter

* Add v2 version of fake driver attribute

* Make direct replacement and wire up window resizing events

* Update casts to use V2 fake driver instead

* Adjust interfaces to expose less internals

* Fix not raising iteration event in v2

* WIP investigate what it takes to do resize and redraw using TextAlignment_Centered as example

* Sketch adding component factory

* Create relevant fake component factories

* Add window size monitor into factory

* Fake size monitor injecting

* Add helper for faking console resize in AutoInitShutdown tests

* Fix size setting in FakeDriverV2

* Switch to new method

* Fix IsLegacy becoming false when using blank constructor

* Fix for Ready not being raised when showing same top twice also fixes garbage collection issue if running millions of top levels

* Fix tests

* Remove auto init

* Restore conditional compilation stuff

* Restore 'if running unit tests' logic

* Check only for the output being specific classes for the suppression

* Fix support for Esc in facade SendKeys

* Fix AutocompleteTests

* Fix various tests

* Replace LayoutAndDraw with run iteration

* Fix unit tests

* Fix SendKeys in facade.

* Manipulate upper and lower cases.

* Add IsValidInput method to the interface.

* Fix SendKeys scenario

* Fixes surrogate pairs in the label

* Make tests more sensible - they are testing draw functionality.  Callbacks do not need to happen in Iteration method

* Fix tests and harden cleanup in AutoInitShutdownAttribute v2 lifecycle dispose

* Delete extra create input call

* Fix mocks and order of exceptions thrown in Run when things are not initialized

* Revert use of `MapConsoleKeyInfoToKeyCode`

* Ignore casing as it is not what test is really about

* Clear application top and top levels before each auto init shutdown test

* Fix for unstable tests

* Restore actually working SendKeys code

* option to pass logger in fluent ctor

* restore ToArray

* Fix SendKeys method and add extension to unit test

* Leverage the EscSeqUtils.MapConsoleKeyInfo method to avoid duplicate code

* Remove unnecessary hack

* Using only KeyCode for rKeys

* Recover modifier keys in surrogate pairs

* Reformat

* Remove iteration limit for benchmarking in v2

* remove iteration delay to identify bugs

* Remove nudge to unique key and make Then run on UI thread

* fix bad merge

* Make logs access threadsafe

* add extra wait to remove race between iteration end and assert

* Code cleanup

* Remove test for crash on access Cancelled after dispose as this is no longer a restriction

* Change resize console to run on UI thread - fixing race condition with redrawing

* Restore original frame rate after test

* Restore nudge to unique key

* Code Cleanup

* Fix for cascading failures when an assert fails in a specific test
