[SPARK-31748][PYTHON] Document resource module in PySpark doc and rename/move classes
### What changes were proposed in this pull request?

This PR is kind of a followup for SPARK-29641 and SPARK-28234. This PR proposes:

1.. Document the new `pyspark.resource` module introduced at 95aec091e4, in PySpark API docs.

2.. Move classes into fewer and simpler modules

Before:

```
pyspark
├── resource
│   ├── executorrequests.py
│   │   ├── class ExecutorResourceRequest
│   │   └── class ExecutorResourceRequests
│   ├── taskrequests.py
│   │   ├── class TaskResourceRequest
│   │   └── class TaskResourceRequests
│   ├── resourceprofilebuilder.py
│   │   └── class ResourceProfileBuilder
│   ├── resourceprofile.py
│   │   └── class ResourceProfile
└── resourceinformation
    └── class ResourceInformation
```

After:

```
pyspark
└── resource
    ├── requests.py
    │   ├── class ExecutorResourceRequest
    │   ├── class ExecutorResourceRequests
    │   ├── class TaskResourceRequest
    │   └── class TaskResourceRequests
    ├── profile.py
    │   ├── class ResourceProfileBuilder
    │   └── class ResourceProfile
    └── information.py
        └── class ResourceInformation
```

3.. Minor docstring fix e.g.:

```diff
-     param name the name of the resource
-     param addresses an array of strings describing the addresses of the resource
+     :param name: the name of the resource
+     :param addresses: an array of strings describing the addresses of the resource
+
+     .. versionadded:: 3.0.0
```

### Why are the changes needed?

To document APIs, and move Python modules to fewer and simpler modules.

### Does this PR introduce _any_ user-facing change?

No, the changes are in unreleased branches.

### How was this patch tested?

Manually tested via:

```bash
cd python
./run-tests --python-executables=python3 --modules=pyspark-core
./run-tests --python-executables=python3 --modules=pyspark-resource
```

Closes #28569 from HyukjinKwon/SPARK-28234-SPARK-29641-followup.
