[inspector] Remove obsolete V8DebuggerScript::isSourceLoadedLazily().

This was originally introduced to address http://crbug.com/794941,
to make the disassembly generation for WebAssembly modules lazy.
Nowadays we no longer generate a text representation for the Wasm
disassembly in V8, and this method always returns `false`.
