refactor initialization out from packer configs + tests (#9627)
The initialization of packer core in JSON also validates that `null` variables were set, except in the case of `packer validate --syntax-only` , but after the refactor to allow to have all commands work with HCL2 and JSON this subtlety was lost.

This refactors the initialisation of the core in order to allow to have `packer validate --syntax-only` not error in case a variable is not set. Since these calls are refactored this works for HCL2 too.

fix #9478

Adrien Delorme 5c2b8da63b get builds from PackerConfig instead of parser
to allow just reading the config and to not start anything. This will allow to later on run `validate --syntax-only`.

Note that none of the builder/provisioner/post-processor config will be read but simply ignored. HCL2 still needs the body to be properly formatted and it should detect most syntax errors.

HCL2: pass on builder type and name (#8956)
* 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:

build using HCL2 (#8423)
This follows #8232 which added the code to generate the code required to parse
HCL files for each packer component.

All old config files of packer will keep on working the same. Packer takes one
argument. When a directory is passed, all files in the folder with a name
ending with  “.pkr.hcl” or “.pkr.json” will be parsed using the HCL2 format.
When a file ending with “.pkr.hcl” or “.pkr.json” is passed it will be parsed
using the HCL2 format. For every other case; the old packer style will be used.

## 1. the hcl2template pkg can create a packer.Build from a set of HCL (v2) files

I had to make the packer.coreBuild (which is our one and only packer.Build ) a public struct with public fields

## 2. Components interfaces get a new ConfigSpec Method to read a file from an HCL file.

  This is a breaking change for packer plugins.

a packer component can be a: builder/provisioner/post-processor

each component interface now gets a `ConfigSpec() hcldec.ObjectSpec`
which allows packer to tell what is the layout of the hcl2 config meant
to configure that specific component.

This ObjectSpec is sent through the wire (RPC) and a cty.Value is now
sent through the already existing configuration entrypoints:

 Provisioner.Prepare(raws ...interface{}) error
 Builder.Prepare(raws ...interface{}) ([]string, error)
 PostProcessor.Configure(raws ...interface{}) error

close #1768


Example hcl files:

```hcl
// file amazon-ebs-kms-key/run.pkr.hcl
build {
    sources = [
        "source.amazon-ebs.first",
    ]

    provisioner "shell" {
        inline = [
            "sleep 5"
        ]
    }

    post-processor "shell-local" {
        inline = [
            "sleep 5"
        ]
    }
}

// amazon-ebs-kms-key/source.pkr.hcl

source "amazon-ebs" "first" {

    ami_name = "hcl2-test"
    region = "us-east-1"

        owners = ["amazon"]
    }

Adrien Delorme 2b0e0d4eab add hcl2template pkg
Package hcl2template defines code to parse hcl2 template files correctly.

In order to configure a packer builder,provisioner,communicator and post
processor.

Checkout the files in testdata/complete/ to see what a packer config could
look like.
