Bump external/Java.Interop from 7049364 to c24a8e9b

Fixes a Release-mode startup crash in MAUI apps on preview.6:

    System.TypeInitializationException: ... Java.Interop.ManagedPeer
    ---> Java.Lang.IncompatibleClassChangeError: no static or non-static
    method "Lnet/dot/jni/ManagedPeer;.????"

Picks up dotnet/java-interop#1474 "Register JNI natives via blittable
JniNativeMethod", which reworks the RegisterNatives chokepoint to marshal
method names/signatures to UTF-8 ourselves and dispatch through the
blittable RegisterNatives(ReadOnlySpan<JniNativeMethod>) overload.

The old path passed a non-blittable JniNativeMethodRegistration[] through
a delegate* unmanaged<> call. dotnet/runtime#126911 moved array-of-struct
marshalling into a managed StructureMarshaler<T> whose blittable-only
fallback is miscompiled by crossgen2 under composite R2R + startup MIBC,
blitting a managed string reference into the native char* name and
corrupting the registered method names (the "????" above). This only
reproduces in Release (composite R2R + PGO), which is why Debug and
`dotnet new android` were unaffected while MAUI Release crashed.
