Support for PyMySQL

### Describe the feature

Support the usage of the pymysql connector

### Use Case

The project I'm working on uses pymysql, I tried to pass the `Connect` class to the `AwsWrapperConnection`, however, it's failing because it's casting the port argument to a `string`, even though I'm passing an `int`.

Code that's turning the port into a string:
```
def prepare_connect_info(self, host_info: HostInfo, props: Properties) -> Properties:
prop_copy: Properties = Properties(props.copy())

prop_copy["host"] = host_info.host

if host_info.is_port_specified():
prop_copy["port"] = str(host_info.port)

PropertiesUtils.remove_wrapper_props(prop_copy)
return prop_copy
```

pymysql code enforcing the int type:
`connections.py`
```
// ...
self.port = port or 3306
if type(self.port) is not int:
raise ValueError("port should be of type int")
// ...
```

I wonder if it's possible to remove that cast to string or adapt somehow to support pymysql. I'm not sure if that's all it's going to take, though.

### Proposed Solution

Remove the cast to string for the port
```
if host_info.is_port_specified():
prop_copy["port"] = host_info.port
```

or a condition for the pymysql library

### Acknowledgements

- [ ] I may be able to implement this feature request
- [X] This feature might incur a breaking change

### The AWS Advanced Python Wrapper version used

1.1.1

### Python version used

3.12

### Operating System and version

Ubuntu 22.04

Start at prepare_connect_info and trace how its port property reaches the PyMySQL connections.py validation. Check the existing connection flow with an integer port and confirm that support works without breaking other connectors; done means a PyMySQL connection accepts the configured port.
