refactor: Rewrite JS API to share server implementation of Flight/Bar…

…rage (deephaven#5890)

Rewrites JS API Flight/Barrage to share code as much as possible with
the JVM client/server implementation. Some classes are effectively
copied with minor updates to function in the browser, such as
WebBarrageStreamReader. Others offer alternative implementations to
generic interfaces, like WebChunkReaderFactory. Finally, super source is
added to handle classes in Deephaven, gRPC, and Java itself, to allow
use of those types in the browser.

Notably, JS clients subscriptions are now the same implementation for
both viewports and full table subscriptions. This change may degrade
performance of viewports in some case relative to previous versions. To
help mitigate this, in certain cases the configuration property
`web.flattenViewport` may improve things. This lets the server instruct
all clients to flatten their tables before subscribing.

Fixes deephaven#188
Fixes deephaven#186
