JoostK 1381301afe refactor(compiler-cli): track a dependency on a default import on `WrappedNodeExpr` (#41557)
Previously, the `DefaultImportRecorder` interface was used as follows:

1. During the analysis phase, the default import declaration of an
   identifier was recorded.

2. During the emit phase each emitted identifier would be recorded.
   The information from step 1 would then be used to determine the
   default import declaration of the identifier which would be
   registered as used.

3. A TypeScript transform would taint all default imports that were
   registered as used in step 2 such that the imports are not elided
   by TypeScript.

In incremental compilations, a file may have to be emitted even if its
analysis data has been reused from the prior compilation. This would
mean that step 1 is not executed, resulting in a mismatch in step 2 and
ultimately in incorrectly eliding the default. This was mitigated by
storing the mapping from identifier to import declaration on the
`ts.SourceFile` instead of a member of `DefaultImportTracker` such that
it would also be visible to the `DefaultImportRecorder` of subsequent
compiles even if step 1 had not been executed.

Ultimately however, the information that is being recorded into the
`DefaultImportRecorder` has a longer lifetime than a single
`DefaultImportRecorder` instance, as that is only valid during a single
compilation whereas the identifier to import declaration mapping
outlives a single compilation. This commit replaces the registration of
this mapping by attaching the default import declaration on the output
AST node that captures the identifier. This enables the removal of
all of the `DefaultImportRecorder` usages throughout the analysis phase
together with the `DefaultImportRecorder` interface itself.
