[edk2-platforms PATCH] Platform/ARM: Update Readme.md

["Rebecca Cran" <rebecca@bsdio.com>]

The repo with the Visual Studio support no longer exists.
fiptool from the prebuilt_tools repo doesn't work due to a missing
dependency on libcrypto.so.1.0.0, so tell users to build it from the
trusted-firmware-a repo instead.
There's a newer version of fvp-uefi.zip that was released in 2020.
