Desktop: Touch slop support for touch devices on desktop platforms

[igordmn]

Android uses specific distance to differentiate between touch drag and touch click (ViewConfiguration.touchSlop). On desktop we significally decrease the touch slop in https://android-review.googlesource.com/c/platform/frameworks/support/+/1698450. Unwanted drags on desktop are usually prevented by the friction between mouse and surface.

The open question - should we use a different touch slop when we use a touch screen on desktop? (for example on Microsoft Surface)

We should investigate on the real touch devices:

• to know if touch slop is implemented on the driver level, or not
• if not - should we use a bigger slop in Compose
• to know how macOs/Windows/Linux handle this
