Add INPUT_FEATURE_NO_INPUT_CHANNEL to SplitDecorManager 

SplitDecorManager hosts the resize app icon for each split task, which
doesn't need input features. Adding this flag saves an IPC to
IWindowSession#grantInputChannel.

Bug: 335975211
Test: resize split works, perfetto trace doesn't show this binder
transaction anymore
