mb/google/nissa/var/anraggar: Enable BT audio offload 

This patch enables Cnvi BT Audio Offload feature and also
configures the virtual GPIO for CNVi Bluetooth I2S pads.

BUG=b:303157827
TEST=Build and boot to anraggar. Verify the config from serial logs.

w/o this CL -
```
[SPEW ]  -- CNVi Config --
[SPEW ]  CNVi Mode= 1
[SPEW ]  Wi-Fi Core= 1
[SPEW ]  BT Core= 1
[SPEW ]  BT Audio Offload= 0
[SPEW ]  Pin Muxing
```
