fix(esp_security): Enable Key Manager clocks even for efuse key operations

Browse Source 
The Key Manager holds a key usage register, thus, the Key Manager peripheral
clock must be enabled even for efuses-based key operations to route the
crypto operations to correctly to the efuses (default is Key Manager)
