fix: [SVLS-5953] pointers for deserialized DynamoDB requests

[apiarian-datadog]

Fixes #11320 .

The resource-based APIs for DynamoDB in boto3 accept deserialized python values and turn them into proper type-tagged DynamoDB API objects in the background. Unfortunately we don't seem to have access to those lower-level type-tagged objects, so if we see the deserialized forms we need to transform them ourselves in order to correctly extract the key values for hashing into span pointers.
