Ensure setting opts on DynamicMap does not generate deprecation warnings

[philippjfr]

The DynamicMap._style method is responsible for applying options set on a DynamicMap. It does so by looking up a custom options tree and then setting that on the returned object. The format of that custom options tree is broken down by the options group (i.e. 'style', 'norm' and 'plot') and then gets applied using the public .opts() call. This is problematic because .opts explicitly checks that options are not set using the deprecated option groups format. Therefore we bypass that call and directly apply the option groups using opts.apply_groups (which is what happens internally anyway).

Fixes #5341

Thanks for the clear explanation and the change looks fine. Happy to see this merged when the tests pass.
