Hrishikesh Dhayagude da6cb6c741 components/bt: Improve the Bluetooth debug messaging scheme 
As of now, when Bluetooth debugs are enabled, all the messages are
mapped to BT_PRINTF which is mapped to ESP_LOGE. Hence, make monitor
shows all logs in red color which might lead to missing the actual
errors

This patch maps the Bluetooth messages to appropriate ESP_LOG* messages
and improves readability.

Also, make the BT trace level be configurable in menuconfig, so that
each layer of bt trace can be enabled/disabled.

Finally, add debug log control for BTC, OSI, BLUFI and clear up
Bluetooth debug logs.

So, with this the method of enabling Bluetooth logs is as follows:
1. make menuconfig -> Component config -> Bluetooth -> Bluedroid Enable
-> BT DEBUG LOG LEVEL -> set trace level for every layer of BT
