fix(instrumentation): allow different export types for files within a Node module

[haines]

Which problem is this PR solving?

The InstrumentationModuleDefinition<T> interface defines a property files: InstrumentationModuleFile<any>[].

InstrumentationNodeModuleDefinition<T> implements this interface but defines the property as files: InstrumentationModuleFile<T>[]. This implies that all files within the module have the same exports type, which is unlikely! As a result, you cannot (for example) call .push() on the files field without type casting.

Short description of the changes

This PR changes the type of the property in the class to match the interface it implements.

@pichlermarc could you please take a look?

[pichlermarc]

I can see this being useful. Pinging @dyladan as I seem to remember we talked about this at some point - he might have some input on the matter.

[pichlermarc]

@dyladan I seem to remember that we discussed changing this to <T=any> at some point so that it can be left out for reasons like this. WDYT?

[haines]

Hi @pichlermarc @dyladan, is there anything blocking getting this merged?

[pichlermarc]

@haines we'll likely remove this type-parameter completely as we've had multiple probems with this in the past. See #4598 for a full write-up.
