The old findGenericCalls second-pass only looked in non-generic functions
and generated unresolved instances like Array_Get_T when generic funcs
called other generic funcs. Removed it entirely.
lowerExpr for ekCall now invokes generateMethodInstance directly for
both explicit (ekGenericCall) and inferred generic calls. This ensures
concrete instantiations are generated on-demand with correct typeSubst.
Also added guard in resolveTypeExpr/substituteType to skip emitting C
struct definitions for unresolved type parameters (e.g. Array<T> inside
a generic function body before monomorphization).
