feat(attributes): Add AWS Lambda, Step Functions and Secrets Manager name attributes

[pabloDeputter]

Description

Adds the following attributes (non-OTel):

• aws.lambda.function.name: the function a Lambda API call acts on (GetFunction, UpdateFunctionCode, …)
• aws.step_functions.state_machine.name
• aws.step_functions.activity.name
• aws.secretsmanager.secret.name: from the Name Secrets Manager returns

Why

Next PR (#717) in stack adds descriptions for AWS SDK spans by service, operation and resource, e.g. SecretsManager.GetSecretValue db-password. Other services already have a short name for this (aws.s3.bucket, aws.kinesis.stream_name, faas.invoked_name). These only had the full ARN, e.g. arn:aws:secretsmanager:us-east-1:123456789012:secret:db-password-AbCdEf, which is too long and already in the respective ARN attribute.

All of these resource names are already part of the ARNs we collect, so no new data is sent.

Lambda constant rebound to new key

High Severity

aws.lambda.function.name normalizes to the same public constant as the existing aws.lambda.function_name key. AWS_LAMBDA_FUNCTION_NAME now means the new SDK-target name, and the old key moves to _AWS_LAMBDA_FUNCTION_NAME. Callers keep compiling but record a different attribute, and the Python deprecation warning no longer fires for the old identifier. These keys are not aliases: the old one still aliases faas.name.
