CMake 3.19 CMAKE_CUDA_ARCHITECTURES causes compiler detection regression

Starting in CMake 3.19 compiler detection for CUDA now has different behavior based on the existence of the CMAKE_CUDA_ARCHITECTURES. When CMAKE_CUDA_ARCHITECTURES is specified CMake will now error out when CMAKE_DETERMINE_COMPILER_ID fails ( via CMAKE_CUDA_COMPILER_ID_REQUIRE_SUCCESS), this is seems safe but has some un-intended side-effects.

Consider the following project:

cmake_minimum_required(VERSION 3.18)

# Emulate a Toolchain file
# Validate that CUDA_FLAGS are handled properly 
# when CMAKE_CUDA_ARCHITECTURES is defined by the user
set(CMAKE_CUDA_FLAGS [=[-DVAR="With Spaces"]=])
set(CMAKE_CXX_FLAGS [=[-DVAR="With Spaces"]=])

set(CMAKE_CUDA_ARCHITECTURES 52)

project(UserCudaArch CXX CUDA)

add_executable(UserCudaArch main.cu)

This project correctly configures with CMake 3.18, but fails with 3.19. If we look at the output logs both CXX and CUDA incorrectly transform -DVAR="With Spaces" but only CUDA errors out since CMAKE_CUDA_ARCHITECTURES has been specified.
