Bluetooth: hci_sync: Convert MGMT_OP_SET_LOCAL_NAME

Uses existing *_sync functions, but made hci_update_name_sync
non-static.

mgmt-test paths:
Set Advertising on - Local name 1
Set Advertising on - Name + Appear 1
Set Local Name - Success 1
Set Local Name - Success 2
Set Local Name - Success 3
Add Advertising - Success (Empty ScRsp)
Add Advertising - Success (Complete name)
Add Advertising - Success (Shortened name)
Add Advertising - Success (Short name)
Add Advertising - Success (Name + data)
Add Advertising - Invalid Params (Name + data)
Add Advertising - Success (Name+data+appear)
Read Ext Controller Info 3
Read Ext Controller Info 4
Read Ext Controller Info 5
Add Ext Advertising - Success (Empty ScRsp)
Add Ext Advertising - Success (Complete name)
Add Ext Advertising - Success (Shortened name)
Add Ext Advertising - Success (Short name)
Add Ext Advertising - Success (Name + data)
Add Ext Advertising - Invalid Params (Name + data)
Add Ext Advertising - Success (Name+data+appear)
