Apply __cdecl to all exported callbacks (#1966)
Resolves CDRIVER-2737 and CDRIVER-5678. Add `BSON_CALL` to public callbacks to support consumers building with non-cdecl calling convention. libmongoc and libbson are expected to only be built with cdecl. --------- Co-authored-by: Ezra Chung <[email protected]>

* Old behavior: `authMechanismProperties=A:B,C:D:E,F:G` is parsed as `{'A': 'B', 'C': 'D:E,F:G'}`.

* Calling `mongoc_bulk_operation_execute` on the same `mongoc_bulk_operation_t` repeatedly is an error. Previously this was only discouraged in documentation.

* Consistently apply `__cdecl` calling convention to function declarations in public API. Intended to support consumers building their code using a different [default calling convention](https://learn.microsoft.com/en-us/cpp/build/reference/gd-gr-gv-gz-calling-convention) with MSVC. The mongoc and bson libraries only support being built with the `__cdecl` default calling convention.
