AccuDraw improvements

[GerardasB]

Is your feature request related to a problem? Please describe.

This is a general issue for AccuDraw improvements.

Currently known problems:

• AccuDraw doesn't remember last-used coordinate input mode, which might require user to run the keyin or shortcut (A+T) to change the mode between sessions. https://www.itwinjs.org/reference/core-frontend/accudraw/compassmode/
• When one of AccuDraw fields is focused it is easy to navigate outside of accudraw widget by simply pressing tab.
• When AccuDraw widget is displayed the auto-focus feature is changing the activeElement/focus before a tool that requires accudraw is activated.

Describe the Solution you'd like

• Remember last-used coordinate input mode between sessions.
• Pressing Tab should toggle between AccuDraw input fields (instead of focusing other elements)
• AccuDraw fields should not be focused until a tool that requires AccuDraw is activated
