vm: pass parsing_context to ScriptCompiler::CompileFunctionInContext

ContextifyContext::CompileFunction in src/node_contextify.cc
was incorrectly passing the context variable to
ScriptCompiler::CompileFunctionInContext

This meant that the parsingContext option in vm.compileFunction
was not being applied properly to the compiled function.

fixes: #23194
