lib: suppress source map lookup exceptions

[legendecas]

lib: skip parsing invalid source maps

When the source map data are invalid json strings, skip construct
SourceMap on it. Additionally, suppress exceptions on source map lookups
and fix test runners crash on invalid source maps.

lib: optimize prepareStackTrace on builtin frames

Only invalidates source map lookup cache when a new source map is found.
This improves when user codes interleave with builtin functions, like
array.map.
