### Tell us about your request

- Implement `From` for `AttributeValue` for common types
- Blob -> AttributeValue::B
- bool -> AttributeValue::Bool
- Vec -> AttributeValue::Bs
- Vec -> AttributeValue::L
- HashMap, AttributeValue::M
- all number types -> AttributeValue::N
- Vec -> AttributeValue::Ns
- String -> AttributeValue::S
- Vec -> AttributeValue::SS
- (I left out AttributeValue::Null since that would conflict with AttributeValue::Bool)
- Let all methods that currently take `AttributeValue` instead take `Into`

That will allow methods such as [expression_attribute_values](https://docs.rs/aws-sdk-dynamodb/latest/aws_sdk_dynamodb/client/fluent_builders/struct.Query.html#method.expression_attribute_values) to be used like this

```rust
expression_attribute_values(":name", "some name".to_string())
```
instead of the current

```rust
expression_attribute_values(":name", AttributeValue::S("some name".to_string()))
```

### Tell us about the problem you're trying to solve.

Make constructing `AttributeValue`s more ergonomic.

### Are you currently working around this issue?

Converting to `AttributeValue` manually.

### Additional context

_No response_

Start with aws_sdk_dynamodb::model::AttributeValue and the Query fluent builder's expression_attribute_values entry point. Implement the listed common-type conversions and update methods that currently take AttributeValue to accept Into, so callers can pass values such as a String directly.
