This commit migrates all our examples to using `wasm-pack build` to
compile their code and run `wasm-bindgen`. This should make it a bit
easier to understand the examples as there's less to follow during the
build step.
Webpack projects are all using `@wasm-tool/wasm-pack-plugin` as well so
the build step is simple `npm run serve`. Other examples which retain
`build.sh` are just using `wasm-pack build` now
This commit implements the first half of [RFC #5] where the `Deref`
trait is implemented for all imported types. The target of `Deref` is
either the first entry of the list of `extends` attribute or `JsValue`.
All examples using `.as_ref()` with various `web-sys` types have been
updated to the more ergonomic deref casts now. Additionally the
`web-sys` generation of the `extends` array has been fixed slightly to
explicitly list implementatoins in the hierarchy order to ensure the
correct target for `Deref` is chosen.

This commit updates all examples to not use `path` dependencies but
rather use versioned dependencies like would typically be found in the
wild. This should hopefully make the examples more copy-pastable and
less alien to onlookers!
The development of the examples remains the same where they continue to
use the `wasm-bindgen`, `js-sys`, `web-sys`, etc from in-tree. The
workspace-level `[patch]` section ensures that they use the in-tree
versions instead of the crates.io versions.
This commit employs the strategy described in #908 to apply a
non-breaking change to fix WebIDL to be compatible with all browsers,
including Safari.
The problem here is that `BaseAudioContext` and `AudioScheduledSourceNode`
are not types in Safari, but they are types in Firefox/Chrome. The fix
here was to move the contents of these two interfaces into mixins, and
then include the mixins in all classes which inherit from these two
classes. That should have the same effect as defining the methods
inherently on the original interface.
Additionally a special `[RustDeprecated]` attribute to WebIDL was added
to signify interfaces this has happened to. Currently it's directly
tailored towards this case of "this intermediate class doesn't exist in
all browsers", but we may want to refine and extend the deprecation
message over time.
Although it's possible we could do this as a breaking change to
`web-sys` I'm hoping that we can do this as a non-breaking change for
now and then eventually on the next breaking release batch all these
changes together, deleting the intermediate classes. This is also
hopefully a good trial run for how stable web-sys can be when it's
actually stable!

This commit does a few things, including:
* Fixing the generated JS of `wasm-bindgen` to allow polyfills to work.
(a minor tweak of the generated JS)
* All examples are updated to include a Webpack-specific polyfill for
these two types to get examples working in Edge.
* A new page has been added to the guide about supported browsers. This
mentions known caveats like IE 11 requiring `wasm2js` as well as
documenting some `TextEncoder` and `TextDecoder` workarounds for Edge.
Closes#895
Some examples have been failing to load in some browsers, and this
ensures that whenever the promise to load Rust code fails we log any
errors happening instead of accidentally failing silently.
This helped debug a bit in #897
