[master] feat: Improve macOS defaults support

[cdalvaro]

What does this PR do?

Improve macOS defaults support by adding typecasting as well as dictionaries and arrays parsing.

Previous Behavior

Dictionaries and arrays were not supported.

New Behavior

Now you can set dictionaries and arrays, and support for floats and integers values has been improved.

Some examples that works now:

Rectangle - Almost Maximize height:
  macdefaults.write:
    - name: almostMaximizeHeight
    - domain: com.knollsoft.Rectangle.plist
    - value: 0.80
    - vtype: float
    - user: cdalvaro
    - require:
        - pkg: Rectangle

Rectangle - Almost Maximize shortcut:
  macdefaults.write:
    - name: almostMaximize
    - domain: com.knollsoft.Rectangle.plist
    - value:
        keyCode: 36
        modifierFlags: 786432
    - vtype: dict
    - user: cdalvaro
    - require:
        - pkg: Rectangle

The recipe Rectangle - Almost Maximize height didn't work because when comparing the current value with the new one, the new one was a float and the retrieved by macdefaults.read was a string. Thus, the comparison doesn't match.

The recipe Rectangle - Almost Maximize shortcut was not working at all. The write command wasn't formed well. And the output retrieved by macdefaults.read was not parsed into a Python dictionary, so comparison always fails.

Other recipes that works now:

Empty dict set:
  macdefaults.write:
    - name: PROPERTY
    - domain: DOMAIN
    - value: {}
    - vtype: dict

Add new elements to existing dict:
  macdefaults.write:
    - name: PROPERTY
    - domain: DOMAIN
    - value:
      - existingKey: 1
      - newKey: 'Hi'
    - vtype: dict-add

Array set:
  macdefaults.write:
    - name: PROPERTY
    - domain: DOMAIN
    - value:
      - 1
      - 2
      - 3
    - vtype: array

Add an array to existing array:
# Order matters, if the new array is not contained
# in the existing array with the same order it will be appended
  macdefaults.write:
    - name: PROPERTY
    - domain: DOMAIN
    - value:
      - 5
      - 6
    - vtype: array-add

⚠️ Breaking changes

Values are typecasted when possible, so some formulas may need to be adapted to be idempotent.

The type parameter in the macdefaults.write method has been deprecated in favor of vtype. This makes the state and the module coherent and avoids the collision between the parameter and the built-in type() Python function.

The type parameter should be removed in version 3009.
