Purpose of this PR

CMCL-1618: Fix default GameController mapping

This PR addresses a number of issues with the default input mappings provided in the Cinemachine package. The updates included are:

• Renamed the Action Map of the Cinemachine Default Input Actions asset from Player to CM Default to make it clear that these actions originate from the Cinemachine package and not the Player default input actions from the Input System package.
• Removed the negative inversion from the gamepad x axis input.
• Changed the Aim input action on the gamepad to use the left trigger rather than the right shoulder button.
• Changed the Jump input action on the gamepad to use the A button rather than the Y button.
• Changed the Sprint input action on the gamepad to use the X button rather than the A button.
• Fixed the Radial Axis input axis (mapped to the Zoom action) in the Orbital Follow component to map to the y axis rather than the x axis.
• Updated the default radial range max value from 1 to 3.
• Reduced the default Legacy Gain value for non-momentary inputs from 200 to 50.
• Updated the sample projects with the improvements listed above.
