* sets `packer_build_name` and `packer_builder_type` variables for builder provisioners and post-processors in HCL2
* allows to use the new `${source.type}` and `${source.name}` variables in HCL2
* fixes #8932
Note that the common.PackerConfig is used everywhere and was not set for HCL2, this had some implications:
For #8923 you can see the issue here:
dde74232f2/builder/lxd/config.go (L61-L63)
More random examples of where this could cause an issue :
