This provides `proxmox_schema::property_string::PropertyString<T>` for
a typed property-string.
To facilitate this, this introduces
`proxmox_schema:🇩🇪:SchemaDeserializer` which is a serde deserializer
for property strings given a schema.
This basically maps to one of `de::SeqAccess` (for array schemas) or
`de::MapAccess` (for object schemas).
Additionally, a `de::NoSchemaDeserializer` is added, since properties
within the strings may have string schemas with no format to it, while
the type we serialize to may ask for an array (a simple "list") via
serde.
The deserializers support borrowing, for which a helper `Cow3` needed
to be added, since property strings support quoting with escape
sequences where an intermediate string would be allocated and with an
intermediate lifetime distinct from the `'de` lifetime.
A `de::verify` module is added which uses serde infrastructure to
validate schemas without first having to deserialize a complete
`serde_json::Value`.
For serialization, `proxmox_schema::ser::PropertyStringSerializer` is
added split into similar parts `ser::SerializeStruct` and
`ser::SerializeSeq` at the top level, and the same prefixed with
`Element` for inside the actual string. This should also properly
quote the contents if required.

This allows free form text to exist within property strings,
quoted, like:
key="A value with \"quotes, also commas",key2=value2
or also:
"the value for a default_key",key2=value2
And drop ';' as a key=value separator since those are meant
for arrays inside property strings...
