Openthread: [api] unify enable/disable API style

[bukepo]

Is your feature request related to a problem? Please describe.
Currently we have two styles for enable/disable. Most uses two separate APIs. But otLinkRawSetEnable(bool) and otLinkRawSrcMatchEnable(bool) accepts a parameter to disable the functionality, shall we unify the style by adding two disable APIs?

The following APIs seem to follow the SetEnabled(bool) model:

• otChannelManagerSetAutoChannelSelectionEnabled
• otChannelMonitorSetEnabled
• otIp6SetEnabled
• otIp6SetMulticastPromiscuousEnabled
• otIp6SetReceiveFilterEnabled
• otIp6SetSlaacEnabled
• otLinkSetEnabled
• otLinkRawSetEnable
• otLinkRawSetPromiscuous
• otThreadSetEnabled
• otThreadSetRouterRoleEnabled
• otPlatRadioEnableSrcMatch
• otPlatRadioSetPromiscuous

Thanks! Which style is recommended for new APIs?

[jwhui]

I think the preference has been the SetEnabled(bool) style, rather than two separate APIs.

Thank you for the confirmation!
