[SyntheticModules] Address follow-up comments from "Implements ValueWrapperSyntheticModuleScript::Create" CL

The following CL:
https://chromium-review.googlesource.com/c/chromium/src/+/1694604
Contains a few comments left by nhiroki@chromium.org which didn't make it into the CL until after it was merged. This is a follow-up CL designed to address these comments.

The comments are:

third_party/blink/renderer/core/script/value_wrapper_synthetic_module_script.cc:
Line 22:
"Non-member variables shouldn't have trailing `_`, so this should be `options`."

Line 55:
"According to the spec, the base URL and fetch options are null, while in this CL they are set to non-null things. Is this intentional?"
