Upstream Chromium cr147 (https://chromium-review.googlesource.com/c/chromium/src/+/7559078) made FOREGROUND_SERVICE_CAMERA unconditional for all Android builds by removing the is_desktop_android guard. However, the feature that actually uses it (kAndroidEnableBackgroundMediaCapturing) is disabled by default and not enabled by Brave, so the permission is declared but never used. This blocks Play Store publishing because Google requires a declaration with a demo video for any app using FOREGROUND_SERVICE_CAMERA. This PR: - Re-gates FOREGROUND_SERVICE_CAMERA behind is_desktop_android so it's excluded from Brave builds - Removes AndroidManifest_user_permissions.xml since upstream now declares FOREGROUND_SERVICE_MICROPHONE unconditionally, making Brave's duplicate unnecessary Resolves: https://github.com/brave/brave-browser/issues/54143
