HCL2: generate hcl tags with go-cty tags too (#9306)
This will allow to generate the config files:

```go
package main

import (
	"fmt"

	"github.com/hashicorp/hcl/v2/gohcl"
	"github.com/hashicorp/hcl/v2/hclwrite"
	"github.com/hashicorp/packer/builder/alicloud/ecs"
)

func main() {
	name := "name"
	app := ecs.FlatConfig{
		AlicloudImageName: &name,
		ECSSystemDiskMapping: &ecs.FlatAlicloudDiskDevice{
			DiskName: &name,
		},
	}

	f := hclwrite.NewEmptyFile()
	block := gohcl.EncodeAsBlock(&app, `source "something" "something"`)
	f.Body().AppendBlock(block)
	fmt.Printf("%s", f.Bytes())
}

```

Will output:

```
source "something" "something" {
  packer_user_variables      = null
  packer_sensitive_variables = null
  image_name                 = "name"
  image_share_account        = null
  image_unshare_account      = null
  image_copy_regions         = null
  image_copy_names           = null
  tags                       = null
  tag                        = null
  system_disk_mapping        = { disk_category = null, disk_delete_with_instance = null, disk_descri
ption = null, disk_device = null, disk_encrypted = null, disk_name = "name", disk_size = null, disk_
snapshot_id = null }
  image_disk_mappings        = null
  ssh_remote_tunnels         = null
  ssh_local_tunnels          = null
  ssh_public_key             = null
  ssh_private_key            = null
}
```

This is a good first step for #9015 and #9282 

fix #9304

HCL2: when we see a map generate an attribute spec instead of a block spec (#9035)
* mapstructure-to-hcl2: when we see a map generate an attribute spec and not a block spec

this will alow to do

tags = {
 key = "value"
}

instead of

tags {
  key = "value"
}

This will also enable using variables directly for those tags

* generate code

* update tests

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"
    instance_type = "t2.micro"

    kms_key_id = "c729958f-c6ba-44cd-ab39-35ab68ce0a6c"
    encrypt_boot = true
    source_ami_filter {
        filters {
          virtualization-type = "hvm"
          name =  "amzn-ami-hvm-????.??.?.????????-x86_64-gp2"
          root-device-type = "ebs"
        }
        most_recent = true
        owners = ["amazon"]
    }
    launch_block_device_mappings {
        device_name = "/dev/xvda"
        volume_size = 20
        volume_type = "gp2"
        delete_on_termination = "true"
    }
    launch_block_device_mappings {
        device_name = "/dev/xvdf"
        volume_size = 500
        volume_type = "gp2"
        delete_on_termination = true
        encrypted = true
    }

    ami_regions = ["eu-central-1"]
    run_tags {
        Name = "packer-solr-something"
        stack-name = "DevOps Tools"
    }
    
    communicator = "ssh"
    ssh_pty = true
    ssh_username = "ec2-user"
    associate_public_ip_address = true
