Remove ballast extension entirely from components.

[atoulme]

Description:
Remove the deprecated memory ballast extension from bundled components, which was replaced by GOMEMLIMIT

[crobert-1]

One more reference that needs removed here:

splunk-otel-collector/internal/components/components_test.go

Line 40 in d4fc4de

"memory_ballast",

[dmitryax]

We also have some env var magic around the ballast extension that we need to clean up

Looks good to me. While there's still some references to the ballast, it's mostly in testdata or readmes, or for backwards compatibility
