Bluetooth: refactor set_exp_feature with a feature table

[ Upstream commit 93fb70bc112e922def6e50b37e20ccfce0c67c0a ]

This patch refactors the set_exp_feature with a feature table
consisting of UUIDs and the corresponding callback functions.
In this way, a new experimental feature setting function can be
simply added with its UUID and callback function.
