* Python: Allow custom argument marshaling for skill scripts
Add an optional argument_marshaler hook so callers can plug in their own argument conversion logic for inline skill scripts. Supplied at the InlineSkillScript, InlineSkill, and ClassSkill levels; when omitted, behavior is unchanged. This supports backends (e.g. vLLM) that send tool-call arguments in a non-conforming shape such as a JSON string.
Port of .NET PR #6498. Closes#6543.

* Address review feedback on skill argument marshaling
- Widen InlineSkillScript.run args to accept a raw str (the one place a marshaler-converted value is valid), and drop the now-unneeded type: ignore markers in tests.
- Constrain the SkillScriptArgumentMarshaler output type to dict | None so the type enforces the inline-script contract instead of a docstring note.
- Add a clear TypeError when a str reaches an inline script with no marshaler configured.

* Rename SkillScriptArgumentMarshaler to SkillScriptArgumentParser
In Python 'marshalling' specifically connotes the stdlib marshal module, so the term is misleading here. Rename the type alias, the argument_parser parameter/attribute, docstrings, exports, and tests accordingly.

* Fold argument_parser docstring into Args section
The skill constructors are fully keyword-only, so name/description/function are already documented under Args. Singling out argument_parser into its own Keyword Args section was inconsistent; merge it into Args for InlineSkillScript, InlineSkill, and ClassSkill.
