Remove override for NativeDOM pointer events casting double to int32_t

[jonthysell]

Problem Description

In the upstream ReactCommon NativeDOM.cpp there are some implicit casts from doubles to PointerIdentifiers (int32_t) which flag as warnings for us. In the integration we disabled warnings, but that causes BinSkim to complain and fail our builds.

I fixed the issue by creating an override and performing the cast, but this issue should be resolved upstream.

Merged on 2/20, can remove once we integrate past this date! :)

@iamAbhi-916 I know you tried to remove the override in the last integrate and it failed some tests. Can you update what went wrong and what needs to be fixed upstream to remove this override?
