RPC Generator should create correct history documentation

[joeljfischer]

Bug Report

Currently the generator for the RPC Spec will add the below documentation when the since attribute is available.
@since SmartDeviceLink X.X

When something is deprecated in the RPC spec this is still the case. This can be confusing because it could be interpreted and something being added and deprecated within the same version. We would like to change this behavior in the generator.
If the deprecated attribute is true and the since attribute is available the documentation should instead include:
@deprecated in SmartDeviceLink X.X

When a parameter is added, the documentation should state:
@added in SmartDeviceLink X.X

RPC Spec Mobile API Versioning Proposal: https://github.com/smartdevicelink/sdl_evolution/blob/master/proposals/0089-mobile-api-versioning.md

Reproduction Steps

1. Run the generator
2. Look at RegisterAppInterface(Response).displayCapabilities documentation

Expected Behavior

Should state @added in SmartDeviceLink 2.0 and @deprecated in SmartDeviceLink 6.0.

Observed Behavior

Does not state the above.
