Add packer fmt command (#10225) 
* Add packer fmt command

This change adds a new command that allows users to format one or more
HCL2 Packer configuration template files.

Related to: #9174

* command/fmt: Add check flag

Packer's fmt command now supports a check flag that will output the name
of any file that would be changed by the HCL2 formatting engine. The
check flag is mutually exclusive with the write flag and will only check
if formatting is needed.

The update write flag will now overwrite the source files with the newly
formatted HCL2 source unless the `-write=false` or `-check` is passed at
the command line.

* Returns a diagnostic error if Format is unable to show a diff - equivalent to `terraform fmt`
* Updates testing to run against #Format and not the private methods of the HCL2Formatter; fixes ShowDiff test failure on Windows
* Updates comments for exported functions

* Add docs for fmt command

HCL2: add post-processors block to run multiple post-processor after a build (#9638) 
added `post-processors` block to run chained post-processors after a build.
Before this, defining multiple `post-processor` blocks after
provisioning steps would run them sequentially, now doing this makes them start
from the build's artifact. To queue post-processors you now have to define them
in a `post-processors` block.

This is a breaking change.

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

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"
