rfctr(html): drop convert_and_partition_html() (#3215)
**Summary**
Remove `unstructured.partition.html.convert_and_partition_html()`. Move
file-type conversion (to HTML) responsibility to each brokering
partitioner that uses that strategy and let them call `partition_html()`
for themselves with the result.

**Additional Context**

Rationale:
- `partition_html()` does not want or need to know which partitioners
might broker partitioning to it.
- Different brokering partitioners have their own methods to convert
their format to HTML and quirks that may be involved for their format.
Avoid coupling them so they can evolve independently.
- The core of the conversion work is already encapsulated in
`unstructured.partition.common.convert_file_to_html_text_using_pandoc()`.
- `convert_and_partition_html()` represents an additional brokering
layer with the entailed complexities of an additional site for default
parameter values to be (mis-)applied and/or dropped and is an additional
location for new parameters to be added.
