Extend DataFrame parameter support to other libraries

[philippjfr]

As we begin to broaden support for different DataFrame libraries in our ecosystem we need to start at the bottom and work our way up. This PR makes it possible for param.DataFrame to be extended with support for other DataFrame libraries and adds initial support for accepting polars DataFrame and LazyFrame objects. For now we maintain backwards compatibility here and require the user to explicitly define which libraries they want to support by providing a libraries argument.

@hoxbro @MarcSkovMadsen would love your thoughts. I'd like to think about Narwhals support but am wondering if that may be better implemented as a new parameter type.

[MarcSkovMadsen]

My POC for how this should be done from param over panel to bokeh is in https://github.com/panel-extensions/panel-graphic-walker/blob/89d6bac66d119d6ad1f75dfe27ec984d18d895ed/src/panel_gwalker/_tabular_data.py#L1

My broader vision for tabular support is in narwhals-dev/narwhals#1289 (comment).

My recommendation would by to first implement this e2e in panel-graphic-walker. That is a place where its really easy to get this working and experimenting e2e. Its also a practical example that will help us have a specific discussion solving real problems.
