Andreas Kling 986e30a140 LibJS: Fix object literal shape caching for numeric string keys ...

Numeric string keys like "0" are converted to numeric property keys and
stored in indexed storage rather than shape-based storage. The shape
caching optimization introduced in 505fe0a977 didn't account for this,
causing properties with numeric keys to be lost on subsequent calls.

The fix excludes object literals with numeric string keys from the
shape caching fast path by checking if any key would become a numeric
property index.
