Description

Summary

Allow react-native-win32.dll to be built for ARM64EC (ARM64 with x64 host app compatibility).

Motivation

Known apps of react-native-win32.dll are not currently being fully built for raw native ARM64.
They currently built for x64 and slowly providing ARM64EC ports.

In order to provide immediate compatibility for either platform on ARM64 devices, the most convenient method is building the RNW DLL for ARM64EC.
