platform/x86: acer-wmi: Add ACER_CAP_SET_FUNCTION_MODE capability flag 

Not all devices supporting WMID_GUID3 support the wmid3_set_function_mode()
call, leading to errors like these:

[   60.138358] acer_wmi: Enabling RF Button failed: 0x1 - 0xff
[   60.140036] acer_wmi: Enabling Launch Manager failed: 0x1 - 0xff

Add an ACER_CAP_SET_FUNCTION_MODE capability flag, so that these calls
can be disabled through the new force_caps mechanism.
