ProjectOptions() having wrong values

[Ondrej Kubik]

ProjectOptions() reports host machine value, ignoring --target-arch value.
This is inconsistent with values passed later the plugins in the build script
For example for --target-arch armhf
ProjectOptions().is_cross_compiling: False
ProjectOptions().target_arch: arm64
ProjectOptions().cross_compiler_prefix: aarch64-linux-gnu-
ProjectOptions().arch_triplet: aarch64-linux-gnu
ProjectOptions().deb_arch: arm64
ProjectOptions().kernel_arch: arm64

yet in the build.sh values are:
export SNAPCRAFT_ARCH_TRIPLET="arm-linux-gnueabihf"
export SNAPCRAFT_TARGET_ARCH="armhf"

@ondrak, a few questions:
1. This is when building a snap on base core22, correct?
2. Can you try again on snapcraft `latest/edge`? (or post a reproducer snapcraft.yaml and/or command line arguments) There's been many updates to snapcraft 7 this month and I'm having trouble reproducing.
3. `--target-arch` isn't supported for core22, I need to check with Sergio to figure out the expected behavior.
