Subject: [PATCH] LibJS: Drop source ranges from bytecode source maps

Store source map locations as bytecode offset, line, and column.
Runtime consumers only emit the start line and column, so source end
positions and source text offsets do not need to be carried through
Executable source maps, bytecode cache serialization, or the Rust FFI.

Keep SourceCode's internal position cache able to track source text
offsets so callers can still translate source offsets to line and
column pairs when needed. Hash dump-bytecode IDs from the name, first
source position, and bytecode size instead of source slices that need
end offsets.

Bump the bytecode cache format version for the slimmer serialized
source map entry shape.
