Subject: [PATCH 1/2] chore: resolve Object langAliases in function argument
 types

Inner Objects nested inside function-typed arguments are not visited
by createClassesAndEnums, so the api generator never set customType
for them and had to fall back to a hardcoded jsonPath switch (the
Screencast.start.onFrame -> Consumer<ScreencastFrame> case).

Have convertBuiltinType resolve the Java type name from the inner
Object's langAliases when no customType is set, and drop the hardcoded
onFrame case. This works once microsoft/playwright adds alias-java
for the onFrame Object (already proposed upstream).
