Reduce legacy Windows driver ANSI escape sequence intermediate string allocations (#3936)

* Skip WindowsConsole StringBuilder append ANSI escape sequence intermediate string allocations

Appending InterpolatedStringHandler directly to StringBuilder skips the formatting related intermediate string allocation. This should also be usable in other console implementation but currently I have no WSL etc. setup to actually verify correct functionality.

* Add CSI_Set* and CSI_Append* comparison benchmark

* Clean up CSI_SetVsAppend benchmark

* Change benchmark names to match the method group
