While #40141 is filed to address the complete unsafe pattern, fixing the
instances of this within the IndexedDB code is something that can happen
today. It is not safe to store raw GC values inside of RootedVec; they
need to be inside Heap wrappers, and those can't be stored in a vector
that can reallocate without being wrapped inside of a Box.
Testing: Fixes an intermittent crashing test.

Moves interfaces defined by the indexeddb spec to the
`script/dom/indexeddb/` module from `script/dom/`.
Testing: Just a refactor shouldn't need any testing

This implements LazyDOMString (from now on DOMString) as outlined in
https://github.com/servo/servo/issues/39479.
Constructing from a *mut JSString we keep the in a
RootedTraceableBox<Heap<*mut JSString>> and transform
the string into a rust string if necessary via the `make_rust_string`
method.
Methods used in script are implemented on this string. Currently we
transform the string at all times.
But in the future more efficient implementations are possible.
We implement the safety critical sections in a separate module
DOMStringInner which allows simple constructors, `make_rust_string` and
the `bytes` method.
This method returns the new type `EncodedBytes` which contains the
reference to the underlying string in either format.
Testing: WPT tests still seem to work, so this should test this
functionality.

This is part of the future work of implementing LazyDOMString as
outlined in issue #39479.
We use str() method or direct implementations on DOMString for these
methods. We also change some types.
This is independent of https://github.com/servo/servo/pull/39480

Testing: This is essentially just renaming a method and a type and
should not change functionality.

From IndexedDB spec, when we check whether a key path is valid, we have
to check whether it is an ECMAScript identifier name. We have not yet
implemented this logic, and always return true.
This patch uses the function `js::rust::wrappers::JS_IsIdentifier` to
achieve this checking.
Testing: Pass WPT tests that were expected to fail.

`convert_value_to_key` returns a `ConversionResult` now, so keys can be
considered "Invalid" rather than throwing an exception.

The current implementation of evaluate_key_path_on_value was translated
from gecko, and it is incomplete. The unimplemented part occurs many
crashes in WPT tests.
This PR re-implements it according to the spec. It should eliminate many
crashed WPT tests, and increase the code readability.
Testing: Update WPT test expectation
Fixes: #38817 partially, and #25325

Uses clipped time to convert dates that are stored as `f64`s into JS
values.

- Use sqlite instead of heed. (one indexed database = one sqlite
database)
- Implement the backend for indexes
- Use keyranges where needed (as specified by the spec)
- Implement `getKey`
- Fix channel error messaging (led to a bunch of changes to how async
requests are handled)
Note: `components/net/indexeddb/engines/sqlite/serialize.rs` is unused;
I can delete it if needed.
Testing: Switching to sqlite eliminated many panics (exposing some new
failures).
Fixes: #38040

- Dates are now serialized as f64s (like how firefox does it)
- Array buffers are serialized with structured cloning (this is not the
most correct/efficent way to serialize them, however it is currently
better than not supporting array buffers at all)
- Array types are still unimplemented.
Testing: WPT
Fixes: Some panicking

A lot of shared functions were scattered around the dom files; I moved
them into `indexed_db.rs` for clarity.
Fixes: Nothing to my knowledge, just a cleanup
