Apply USAGE_IME_FEEDBACK to HapticFeedbackVibrationProvider

Also Remove FLAG_BYPASS_USER_VIBRATION_INTENSITY_SCALE check logic in
HapticFeedbackVibrationProvider and the flag itself introduced from
CL[1] for clean-up.

Since the current vibration and default vibration for IME feedback
are both medium level currently, means there is no additional
scaling from current settings for the keyboard vibration effect in
VibrationScaler, so scale behavior can keep applying the fixed
vibration amplititude (0.62) as before.

In the next CL, we will remove VibrationAttritubute#CATEGORY_KEYBOARD
and its logic in framework and Settings, since USAGE_IME_FEEDBACK can
fully replace the behavior with preserving scaling keyboard vibration
from settings flexibility.

Bug: 332661766
Test: manual as below steps
   0) Enable "Keyboard vibration" in Vibration & haptics Settings
   1) In launcher, tap google search box to show IME.
   2) typing charactors & verify keyboard is vibrating
   3) use adb command: adb dumpsys vibrator_manager, verify the
      vibration effect history shows as below
    scale:     NONE (adaptive=1.00) |flags:    0  <-- no bypass flag
    usage: IME | category=KEYBOARD ...\
    reason: performHapticFeedback(constant=3): \
    View#performHapticFeedback | \
    played: Primitive=CLICK(scale=0.62, delay=0ms) <-- same amplitudue
Test: atest VibrationSettingsTest, VibrationScalerTest
Test: atest HapticFeedbackVibrationProviderTest
