hil: add frdm_k64f host test (cdc + msc) to tinyusb.json

frdm_k64f as a USB host with a CH9102 CDC (TX-RX loopback) and a Lexar MSC
drive behind a hub; flasher = onboard OpenSDA J-Link. host/cdc_msc_hid passes
(CDC mount+echo, MSC mount + disk-size check). device_info remains a known
device_info/usbh limitation (its synchronous descriptor dump starves a 2nd
device's enumeration) and is not ci_fs-specific.
