feat: Instrument Lambda invocations in AWS SDK

[chynesNR]

Instrument calls to Lambdas and Lambda Aliases from the AWS SDK, with span attributes to allow linking the calls to the actual Lambda (specifically the ARN is what's needed). Includes unit and integration tests. We are able to test without a making a successful call to a lambda, so no live testing resources are necessary.

Changes since the last PR:

• Does not treat the segment as a Leaf, so we will get an additional HTTP span, which is now expected
• Caps the size of the ARN cache
• Limits most errors to log only once
• Does not log the account ID, only if it is present or not

[tippmar-nr]

it would be more performant to check _reportBadAccountId here - if it's false, none of the rest of the validation needs to be done.

[nrcventura]

If that's the case, should the validation be done in the DefaultConfiguration class instead?

[chynesNR]

I had planned on revisiting this after the ID decoding was done. There were a few things I wanted to consider:

• Having the validation in a central place
• We may want to fall back to the other ID method if one is invalid
• The environment variable for the ID may be set after we've read the config
• Depending on how we found the ID, it may be bad at first but good later
