motion_lid: Allow host to configure tablet mode detection threshold
This change adds support for host to configure the tablet mode
threshold angle and hysteresis degree using a new motionsense command
MOTIONSENSE_CMD_TABLET_MODE_LID_ANGLE. Additionally, the EC sets a new
feature bit to indicate support for this refined tablet mode
detection. This feature bit can be used by kernel to expose an
inclinometer device which can eventually help remove the redundant lid
angle calculation in Chrome.
BUG=b:120050761
BRANCH=octopus
TEST=make -j buildall. Additionally, verified that tablet mode lid
angle can be configured by host using ectool. Also, feature flag is
correctly set to indicate support for this feature.
