test(ivy): S-EL0 partition using VHE

Starting from [1], Cactus remains the sample S-EL1 partition.
Ivy remains the sample "S-EL0 partition" either using the shim at S-EL1
(as of today), or leveraging Hafnium VHE (reason for this change).
The same code base is re-used by adding the IVY_SHIM toggle. IVY_SHIM=1
is default using the shim, or 0 to use VHE (and strip the shim out).
Using svc helper from spm/common/aarch64/sp_arch_helpers.S

We must modify generate_json.sh so it only adds the partition
information to the layout file for the sp given in arg1. This allows
the ability for sp's to pass flags to the script such as IVY_SHIM which
is used to vary the dts file included for ivy.

Typical build command for a VHE-enabled Ivy partition:
make CROSS_COMPILE=aarch64-none-elf- PLAT=fvp DEBUG=1 TESTS=spm
    ARM_ARCH_MINOR=5 BRANCH_PROTECTION=1 IVY_SHIM=0 ivy -j8

The intent is to create a dedicated tftf_config build config for the
VHE-enabled build in the CI.
