fix: [SVLS-5953] pointers for deserialized DynamoDB requests [backport 2.16] (#11443)

Backport 5724fd3 from #11420 to 2.16.

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.
