Add support for Windows App Control/WDAC (#84898)

* Add support for Windows App Control/WDAC

Adds preview support for Windows App Control, formerly known as WDAC.
This is a tech preview feature and is designed to test out improvements
needed in future versions of Ansible.

* Use psd1 and parse it through the Ast to avoid any unexpected execution results

* Add tests for various manifest permutations

* Ignore test shebang failure

* Apply suggestions from code review

Co-authored-by: Matt Davis <6775756+nitzmahone@users.noreply.github.com>

* Use more flexible test expectations

* Add type annotations for shell functions

+Function New-AnsiblePowerShellSignature {
+    <#
+    .SYNOPSIS
+    Creates and signed Ansible content for App Control/WDAC.
+
+    .DESCRIPTION
+    This function will generate the powershell_signatures.psd1 manifest and sign
+    it. The manifest file includes all PowerShell/C# module_utils and
+    PowerShell modules in the collection(s) specified. It will also create the
+    '*.authenticode' signature file for the exec_wrapper.ps1 used inside
+    Ansible itself.
+
+    .PARAMETER Certificate
+    The certificate to use for signing the content.
+
+    .PARAMETER Collection
+    The collection(s) to sign. This is set to ansible.builtin by default but
+    can be overriden to include other collections like ansible.windows.
+
+    .PARAMETER Skip
+    A list of plugins to skip by the fully qualified name. Plugins skipped will
+    not be included in the signed manifest. This means that modules will be run
+    in CLM mode and module_utils will be skipped entirely.
+
+    The values in the list should be the fully qualified name of the plugin as
+    referenced in Ansible. The value can also optionally include the extension
+    of the file if the FQN is ambigious, e.g. collection util that has both a
+    PowerShell and C# util of the same name.
+
+    Here are some examples for the various content types:
+
+        # Ansible Builtin Modules
+        'ansible.builtin.module_name'
+
+        # Ansible Builtin ModuleUtil
+        'Ansible.ModuleUtils.PowerShellUtil'
+        'Ansible.CSharpUtil'
+
+        # Collection Modules
+        'namespace.name.module_name'
+
+        # Collection ModuleUtils
+        'ansible_collections.namespace.name.plugins.module_utils.PowerShellUtil'
+        'ansible_collections.namespace.name.plugins.module_utils.PowerShellUtil.psm1'
+
+        'ansible_collections.namespace.name.plugins.module_utils.CSharpUtil'
+        'ansible_collections.namespace.name.plugins.module_utils.CSharpUtil.cs'
+
+    .PARAMETER Unsupported
+    A list of plugins to be marked as unsupported in the manifest and will
+    error when being run. List -Skip, the values here are the fully qualified
+    name of the plugin as referenced in Ansible.
+
+    .PARAMETER TimeStampServer
+    Optional authenticode timestamp server to use when signing the content.
+
+    .EXAMPLE
+    Signs just the content included in Ansible.
+
+        $cert = [X509Certificate2]::new("wdac-cert.pfx", "password")
+        New-AnsiblePowerShellSignature -Certificate $cert
+
+    .EXAMPLE
+    Signs just the content include in Ansible and the ansible.windows collection
+
+        $cert = [X509Certificate2]::new("wdac-cert.pfx", "password")
+        New-AnsiblePowerShellSignature -Certificate $cert -Collection ansible.builtin, ansible.windows
+
+    .EXAMPLE
+    Signs just the content in the ansible.windows collection
+
+        $cert = [X509Certificate2]::new("wdac-cert.pfx", "password")
+        New-AnsiblePowerShellSignature -Certificate $cert -Collection ansible.windows
+
+    .EXAMPLE
+    Signs content but skips the specified modules and module_utils
+        $skip = @(
+            # Skips the module specified
+            'namespace.name.module'
+
+            # Skips the module_utils specified
+            'ansible_collections.namespace.name.plugins.module_utils.PowerShellUtil'
+            'ansible_collections.namespace.name.plugins.module_utils.CSharpUtil'
+
+            # Skips signing the file specified
+            'ansible_collections.namespace.name.plugins.plugin_utils.powershell.file.ps1'
