Xbox One profile incorrectly rejects battery state updates

[ReenigneArcher]

Problem

The Xbox One virtual gamepad profile currently advertises that battery state is unsupported, even though its HID descriptor and input-report format can represent battery strength.

make_xbox_gip_profile() sets supports_battery from include_share_button. Xbox One passes false, while Xbox Series passes true, unintentionally coupling battery support to the presence of the Share button.

As a result:

• profiles::xbox_one().capabilities.supports_battery is false.
• gamepad_profile_support() reports no battery support.
• GamepadStateAdapter::set_battery() and clear_battery() reject Xbox One with unsupported_profile.

However, both Xbox One and Xbox Series:

• use the 17-byte GIP-shaped input report;
• include the Generic Device Controls Battery Strength input in their HID descriptors; and
• write normalized battery strength to byte 16 in pack_xbox_gip_input_report().

Expected behavior

The Xbox One profile should advertise battery support independently of Share-button support, and consumers such as Sunshine should be able to submit the client controller battery percentage through the normal adapter API.

Proposed direction

• Decouple supports_battery from include_share_button in make_xbox_gip_profile().
• Advertise battery support for both Xbox One and Xbox Series profiles.
• Add explicit profile-support and adapter tests for Xbox One battery updates.
• Exercise Xbox One report packing with a non-default battery percentage.
• Verify on a Windows host that a consumer can observe the reported battery level.
• Update the end-user compatibility table after the behavior is verified.

Acceptance criteria

• profiles::xbox_one() reports supports_battery == true.
• GamepadStateAdapter::set_battery() and clear_battery() succeed for Xbox One.
• The configured battery percentage is present in byte 16 of the Xbox One input report.
• Existing Xbox Series battery behavior remains unchanged.
• Automated tests cover the capability and report behavior.
