LibJS: Add missing ValueInlines.h include for Value::to_numeric

When compiling with `-O2 -g1` optimizations (as done in the main
Serenity build), no out-of-line definitions end up emitted for
`Value::to_numeric`, causing files that reference the function but don't
include the definition from `ValueInlines.h` to add an undefined
reference in LibJS.so.
