Fix load event for page with no external scripts but with iframes
...
Previously the "load" event happened when all external scripts were done. In the
case that there was no external script, the "load" event would fire immediately
after parsing.
With iframes, it now waits for external script AND iframes to complete but the
no-external-script code was never updated to consider iframes and would thus
fire load events prematurely.

Add a "wpt" dump mode
...
Adds a not-documented "wpt" mode to --dump which outputs a formatted
report.cases.
This is meant to make working on a single WPT test case easier, particularly
with some coding tool. Claude recommended this output for its own use.
Instead of telling claude to start the browser in serve mode, then run the
wptrunner, and merge the two outputs (and then stop the server), you can do:
zig build run -- fetch --dump wpt "http://localhost:8000/dom/nodes/CharacterData-appendChild.html "
(you still need the wpt server up)

Noop when document.open is called during iframe parsing
...
I'm not sure what the correct behavior is, but this fixes a WPT crash:
/html/browsers/sandboxing/sandbox-inherited-from-required-csp.html
The issue is iframe-specific as, with an iframe, you document.write can be
called during parsing when there's no document._current_script (because it's
being executed from the parent).

Correctly JSON encode URL

I think this code comes from some serialization tweak from when everything was
an std.Uri and by switch to [:0]const u8 everywhere not only was the tweak
unecessary, it was also wrong - possibly resulting in the generation of
invalid JSON.

Re-implement forgiving base64 decode without intermediate allocation
...
Was looking at, what I thought was a related issue, and started to extract this
code to re-use it (in DataURIs). Realized it could be written without the
intermediate allocation. Then I realized the dataURI issue is something else,
but wanted to keep this improvement.
