Fix _endpoint_context_cache using id() which risks stale entries and memory leaks
The _endpoint_context_cache in routing.py used id(func) as dict keys to
cache endpoint context (source file, line number, function name) for
error messages. This has two problems:
1. ID reuse after garbage collection. Python id() returns the memory
address of an object. Once an object is garbage collected, its ID can
be reassigned to a newly created object. If an endpoint function were
deallocated and a new function reused the same ID, the cache would
return stale context (wrong file, line, function name) for error
messages.
2. No eviction. The module-level dict grows unboundedly for every unique
endpoint function. In scenarios where FastAPI instances are
dynamically created and destroyed in a single process (e.g., test
suites running hundreds of apps), endpoint functions and their
closures are kept alive indefinitely by the cache, leaking memory.
Fix: replace the plain dict with a weakref.WeakKeyDictionary keyed on
the function object itself. This solves both problems: keys are looked
up by object identity (no ID collision), and entries are automatically
evicted when the endpoint function is garbage collected, allowing the
function and its closure to be reclaimed.
Endpoint functions always support weak references (regular def / async
def), so WeakKeyDictionary is safe for this use case.
