Import of ritm.js causing slow start up performance of servers that import tracer from 'dd-trace'

[zeusdeux]

ritm.js which gets included in the tree when importing tracer as import tracer from 'dd-trace'; adds about 1s to the startup of any server that uses dd-trace on intel machines. Given that the import of ritm is coming from src/lambda it should not be getting imported when running in a container.

Expected behaviour
ritm.js should not be in the import tree in non-lambda environments

Actual behaviour
ritm.js is in the import tree in non-lambda environments

Steps to reproduce

• import tracer from 'dd-trace'; in any file
• take a performance profile in chrome
• find the import tree as in the screenshot above

Environment
Docker container deployed via k8s to AWS

• Operation system:
  Reproduced on macOS

• Node.js version:
  20.9.0

• Tracer version:
  N/A

• Agent version:
  N/A

• Relevant library versions:
  dd-trace v3.39.0 but given the import structure for this path is unchanged on main, this would occur in the latest release as well
