AST: Only check availability of explicitly exported decls

xymus · xymus · commit 9d4ed9215580 · 2026-01-21T11:30:37.000-08:00
Extending type-checking to non-public decls triggered new errors when
`-target-min-inlining-version min` is enabled. Ensure these checks are only
applied to explicitly exported decls.

Affected test: test/Concurrency/deinit_isolation_availability.swift
