Generate URL Filter-squashed

[samialfattani]

Fixes #2703

This PR adds a function to generate a URL with filter arguements including all types of filters (Like, NotLike, Greater....etc) and including both indexed (flt2_3=xx) and named (flt3_email_like=@example.com)

Usage:

    filtered_url = view.url_for(
        search="exam",
        filters=[
            filters.FilterLike(Model1.test1, "Email", url_value="@example.com"),
            filters.BooleanEqualFilter(Model1.bool_field, "active", url_value=False),
            filters.FloatGreaterFilter(Model1.test5, "Salary", url_value=15.3),
        ],
    )

Output:
/admin/user/?search=exam&flt0_0=@example.com&flt1_21=0&flt2_16=15.3

Output with named parameters:
/admin/user/?search=exam&flt0_test1_contains=@example.com&flt1_bool_field_equals=0&flt4_test2_greater_than=15.3

I think my main issue here is on the implementation being that the URL value is baked into the Filter definition. I'm not sure this feels like the right developer experience/API.

I think we should take this back to an issue and plan out the implementation up front rather than do it on a PR.

I think I'd be more interested in something like this:

    filtered_url = view.url_for(
        search="exam",
        filters=[
            (filters.FilterLike(Model1.test1, "Email"), "@example.com"),
            (filters.BooleanEqualFilter(Model1.bool_field, "active"), False),
            (filters.FloatGreaterFilter(Model1.test5, "Salary", 15.3),
        ],
    )

Ideally with full type support so that type checkers can statically verify that you've passed the correct argument type for the appropriate filter, ie boolean values for a Boolean filter and string values for a like filter.

now this style is adapted. you can check and review

    filtered_url = view.url_for(
        search="exam",
        filters=[
            (filters.FilterLike(Model1.test1, "Email"), "@example.com"),
            (filters.BooleanEqualFilter(Model1.bool_field, "active"), False),
            (filters.FloatGreaterFilter(Model1.test5, "Salary", 15.3),
        ],
    )
