inspector: update inspector_protocol to 8ec18cf

Apply 8ec18cf: "Support STRING16 in the template when converting CBOR
map keys"

Refs: https://chromium.googlesource.com/deps/inspector_protocol/+/8ec18cf0885bef0b5c2a922c5dc3813cbf63e962

We're over 2 years out of date in the tools/inspector_protocol directory
and I have to imagine this will come back to bite us at some point. But
I also don't want to do a huge update all at once, so starting with a
single commit. I might bundle commits together a bit more if this goes
well.
