Adds array support for the existing `copyFormatting` global setting.
This allows users to define which formats they would specifically like
to be copied.
A boolean value is still accepted and is translated to the following:
- `false` --> `"none"` or `[]`
- `true` --> `"all"` or `["html", "rtf"]`
This also adds `copyFormatting` as a keybinding arg for `copy`. As with
the global setting, a boolean value and array value is accepted.
CopyFormat is a WinRT enum where each accepted format is a flag.
Currently accepted formats include `html`, and `rtf`. A boolean value is
accepted and converted. `true` is a conjunction of all the formats.
`false` only includes plain text.
For the global setting, `null` is not accepted. We already have a
default value from before so no worries there.
For the keybinding arg, `null` (the default value) means that we just do
what the global arg says to do. Overall, the `copyFormatting` keybinding
arg is an override of the global setting **when using that keybinding**.

Validated behavior with every combination of values below:
- `copyFormatting` global: { `true`, `false`, `[]`, `["html"]` }
- `copyFormatting` copy arg:
{ `null`, `true`, `false`, `[]`, `[, "html"]`}
