HCL2 variables: split validation from getting value (#10843) 
* HCL2 variables: split validation from getting value, to only

This way we do this only once and log this only once. The errors were being ignored anyways.

* Update types.variables_test.go

Adrien Delorme 91d7332471 add basic code for variable validation parsing 
* hcl2template/addrs.ParseRef will parse a reference and tell for example if we
  are referring to a variable and its name, for now it can only do that and in
  the future it improved when we need to most of it is from the TF code. This
  is used to tell wether a variable vas referenced in a variable validation
  condition; for now.
* Added Validations blocks to the hcl2 Variable struct and code to
  parse/validate that.

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

hcl2template/types.variables: Update logic for parsing literal value variables (#8834) 
* hcl2template/types.variables: Update logic for parsing literal value variables

In running tests via the CLI it was determined that when using the variable block with no explicit type assigned the type of the default
value was not being set within the map. This change updates the `decodeConfig` method so that a type is always set for any defined variable if not specified.

The second change is to properly handle the evaluation of basic variable types (e.g String, Number, Bool). Previously variables defined on the
CLI or via PKR_VAR required some additional quoting to for proper evaluation. This change fixes that issue so that it works like it does in Terraform :)

Build results before the change
```
⇶  PKR_VAR_example='["one","two"]' ~/bin/packer build -var 'foo=home' .
Error: Variables not allowed

  on <value for var.foo from arguments> line 1:
  (source code not available)

Variables may not be used here.

==> Builds finished but no artifacts were created.

```

Build results after the change
```
⇶  PKR_VAR_example='["one","two"]' ~/bin/packer build -var 'foo="home"' .
null: output will be in this color.

==> null: Running local shell script: /tmp/packer-shell885249462
    null: two
    null: home
Build 'null' finished.

==> Builds finished. The artifacts of successful builds are:
--> null: Did not export anything. This is the null builder

⇶  ~/bin/packer build -var 'foo=home' -var 'example=["one","another variable"]' .
null: output will be in this color.

==> null: Running local shell script: /tmp/packer-shell123467506
    null: another variable
    null: home
Build 'null' finished.

==> Builds finished. The artifacts of successful builds are:
--> null: Did not export anything. This is the null builder

```

* tests/hcl2template/types.variables: Update test to use Bool

Turns out a string value won't actually complain if it's given a non
string looking value. It will just covert the value to a string literal
so using a type Bool which should fail if given anything that is not
true or false.

* tests/hcl2template/types.variables: Update unit tests

During testing it was found that by default the variable stanza were defaulting to a cty.NilType, and not the Type of it's default value.
This change sets the default type of the defined variable to ensure variable evaluation behaviors correctly.

* Add a simple cty.Bool test case

* tests/hcl2template/types.variables:  Enable quoted_string test case

* Update hcl2template/types.variables.go

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"
