fix(sql_parse): Support Jinja format() filter when extracting latest[_sub]_partition

[john-bodley]

SUMMARY

One can specify either a Jinja filter or Python str function to dynamically define the table referenced by the latest[_sub]_partition macros. Cases like trino.latest_partition("foo.%s"|format("bar")) and trino.latest_partition("foo.{}".format("bar")) resulted in errors of the form,

AttributeError: 'Filter' object has no attribute 'value'

or

AttributeError: 'Call' object has no attribute 'value'

respectively.

I went through numerous rabbit holes to try to have the Jinja environment render the AST subtree in a generic way, but alas I wasn't able find an elegant solution—especially when it comes to the Call node.

The fix—which only works for the Filter node—is to use the as_const() method as opposed to the value attribute to ensure the filter is rendered. Note that one can always rewrite the str.format using the Jinja format() filter.
