BetterJoy2 v7.3.0

Add per-profile gyro analog sliders toggle

GyroAnalogSliders (gyro-driven L2/R2 output while a stick-gyro button
is held) was a global App.config-only setting. Made it a per-profile
option like GyroHoldToggle/DragToggle/SwapAB/SwapXY: added it to
ControllerMappings.OptionKeys, and switched Joycon.GyroAnalogSliders
from a field cached once at construction to a property that reads the
current profile live, so it responds immediately to a profile change.

Added an Enabled/Disabled control in the profile UI's Gyro page,
listed last in Output activation after Right stick. Styled as a real
SplitButton (StyleMappingButton via AddMappingRow) to match the Mouse/
Left stick/Right stick rows above it pixel-for-pixel, but wired to its
own small two-item menu instead of the Remap combo-capture those rows
use, since this is a plain on/off flag with no bind semantics.
