Reject bool for max_size and header limit args

[Pitchfork-and-Torch]

Summary

bool is a numbers.Number and subclasses int, so:

• max_size=True passed the existing isinstance(..., Number) and max_size >= 1 check (since True >= 1) and silently became size 1
• max_header_count=True / max_header_size=True had no type checks and likewise became 1

This change rejects bool for max_size on OctetStreamParser, QuerystringParser, and MultipartParser, and adds int/non-bool validation for max_header_count / max_header_size.

Test plan

• Added bool-reject tests for Querystring/OctetStream/Multipart parsers
• Related max_size / header tests pass
