Fix notification inline reply animation

This CL fixes the animation for the appearance of the inline reply RemoteInputView, bringing it as close to the Direct spec (https://direct.googleplex.com/#/spec/283080003) as possible. Intentional deviations from the Direct specs are the following:
1. The animation duration is 360 ms instead of 500 ms (in order to be consistent with other notification shade resize animations)
2. The interpolator is FAST_IN_SLOW_OUT, which might differ slightly from the Direct specs "DECELERATE_WITH_EASING" interpolator. (same reason as for 1.)
3. The height of the notification is increased slightly more than in the Direct spec. (This is done in order to keep the paddings and margins as they currently are. It seems to me that if there was more text in the Direct visualization, the top margin of the inline reply EditText would be too small.)

This CL does not fix the following related issues:
1. The collapsed heads up view does not allocate enough space to fit the RemoteInputView. This causes the top part of the notification to get shrunk (Icons jump up by a few pixels), when clicking the "Reply" button. It also affects the beginning of the RemoteInputView expand animation to be partly shifted out of the HeadsUp View.
2. When defocusing the RemoteInputView, the "Reply" button is clipped during the beginning of the animation.
3. When focusing the RemoteInputView, the notification shade is not scrolled correctly. (Keyboard is overlapping RemoteInputView)
4. The expand/collapse animation is broken while the RemoteInputView is visible.
I will address these issues in seperate CLs.

Bug: 174148361
Test: atest RemoteInputViewTest, Manual, i.e. posting various types of Notifications from the Notify2-RVC application with a reply action added to them. Then observing the animations visually and analyzing frames from screen recordings.
