Issue:
Any not supported in provider_map
### Description

Trying to use polyfactory with a model with a `typing.Any` field, I cannot seem to cover it in the `get_provider_map`. Using `object` instead of `Any` works as a workaround, but does not feel right.

### MCVE

```python
from typing import Any

from polyfactory.factories.pydantic_factory import ModelFactory
from pydantic import BaseModel


class WeirdModel(BaseModel):
    any: Any
    obj: object


class Factorio(ModelFactory[WeirdModel]):
    @classmethod
    def get_provider_map(cls) -> dict[type, Any]:
        providers_map = super().get_provider_map()

        return {
            **providers_map,
            Any: lambda: "this does not work",
            object: lambda: "this works as workaround",
        }


print(Factorio().build())
# prints: any='<a random string>' obj='this works as workaround'
# I would expect "this does not work" for any
```


### Steps to reproduce

```bash
Just run the above script (tested with python 3.12) for instance on the command line.
```

### Description
<!--
Please describe your pull request for new release changelog purposes
-->

- We were incorrectly not considering the value provided in the provider map for any field typed as `Any.` This ensures that we consider the value given in the provider map allowing users to override the generated value.
- This also fixes the same issue that may arise if the user wishes to override the value generated for `TypeVar`.
