ac5fa629ef Python: inline init_module_submodule_defn into ImportResolution
The new-dataflow ImportResolution module only used
semmle.python.essa.SsaDefinitions for the 5-line helper predicate
SsaSource::init_module_submodule_defn. Inline it locally and drop the
dependency on legacy SsaDefinitions. This is the only remaining direct
import of semmle.python.essa.* in the new dataflow stack, so dropping
it makes the layering cleaner.

Semantic noop on the current SSA: SsaSourceVariable.getName() and
GlobalVariable.getId() both project the same DB column
(variable(_,_,result)), and the old call's 'init.getEntryNode() = f'
join was just constraining init = package via Scope.getEntryNode()'s
functional uniqueness. RA dump of accesses.ql confirms only the
expected predicate-rename shuffle; all 70 dataflow + ApiGraphs library
tests pass.

This factors out commit 8cab5a20f2 from the larger shared-CFG
migration #21925.
