EFS: Provide name for access point

### Describe the feature

There should be a possibility to provide access point name for the created efs access point

### Use Case

Currently we can provide the name tag to the efs access point to easily identify it. however the name property should be definable when creating the access point itself

### Proposed Solution

add attribute called access_point_name to add_access_point function in FileSystem class

### Other Information

### Acknowledgements

### CDK version used

### Environment details (OS name and version, etc.)

macOS Ventura 13.4.1

Start by locating the FileSystem class and its add_access_point entry point, then inspect how existing access-point options are represented and passed through. The work is done when an access_point_name option can be supplied during creation and the resulting EFS access point receives that name, with focused coverage for the new option.
