tests(devtools): skip type checking in local builds

[adamraine]

devtools_skip_typecheck=true is the only way to really speed up DT builds according to this doc:
https://chromium.googlesource.com/devtools/devtools-frontend/+/main/docs/get_the_code.md#standalone-checkout-build

Validating types is still valuable for each patch, so leaving it on in CI.

One annoying problem is that local builds will spit out a bunch of [WARNING] Unrecognized target environment "es2022" warnings for some reason :/

---

This PR also removes the use_goma=true and requisite user email check because it has been removed from non-windows builds as of recently.

Please replace this with the new remote option instead of removing.

I'm not sure DT frontend can be built on reclient (TBH I don't know if it was every working with goma either)

Following the Chromium instructions for reclient leads to build issues talking about a missing reclient config :/

To build with gn arg 'use_remoteexec=true' as a googler on a corp machine
set "download_remoteexec_cfg" in .gclient like

solutions = [
    {
        "name"        : "src",
        # ...
        "custom_vars" : {
            "download_remoteexec_cfg": True,
        },
    },
]

and re-run `gclient sync`.
