Add missing hal interfaces

[dcaliste]

@jerpelea, this is to allow to compile the system/bt and fm/ parts. I've copied the two bluetooth interfaces from LineageOS and put things a bit on guess for the FM hal interface.

This is another part of sonyxperiadev/vendor-qcom-opensource-bluetooth#4. To get it compile, I've added this to device/sony/pdx201/aosp_xqau52.mk:

TARGET_FWK_SUPPORTS_FULL_VALUEADDS := true
$(call inherit-product, vendor/qcom/opensource/commonsys-intf/bluetooth/bt-commonsys-intf-board.mk)
$(call inherit-product, vendor/qcom/opensource/commonsys-intf/bluetooth/bt-system-opensource-product.mk)

Can we get these by bumping to a newer CAF tag as well? I'd rather apply upstream commits in favour of combating divergence and easier conflict resolution on updates.
