PHP-1107: Explicitly set connectTimeoutMS default value (60000)

Previously, the connectTimeoutMS default was only inferred in mongo_connection_connect() (1 second) and php_mongo_io_stream_connect() (no timeout, but defer to default_socket_timeout INI setting). This explicitly uses the default_socket_timeout default (60000) for connectTimeoutMS.
PHP-1107: Block on non-stream connections when connectTimeoutMS <= 0

This is logically consistent with stream connections, which omit a timeout when connectTimeoutMS <= 0 (although default_socket_timeout would still apply).
PHP-1107: Set connectTimeoutMS option whenever a new value is found

Always log that we found the option, but only report that it is replaced when the value is actually changed.
PHP-1107: Split PHP-1099 tests and update for connect timeout behavior

Connection-related messages will use connectTimeoutMS (default: one second) instead of socketTimeoutMS (default: 30 seconds).
PHP-1107: Update PHP-683 test for new connectTimeoutMS default and logging
PHP-1107: Split testing with/without timeout options
Use equal connect/socket timeouts for legacy log tests

This avoids major adjustments to the expected output when timeouts would be swapped for connection-related operations.
