Subject: [PATCH] sdk: Add wasm target for docs

#### Problem

As pointed out in [this PR
comment](https://github.com/anza-xyz/agave/pull/3634#discussion_r1867791497)
it's good to specify that docs build for wasm32 where needed.

Also, solana-sdk and solana-program don't configure docs builds with all
features enabled.

#### Summary of changes

In most places, add "wasm32-unknown-unknown" as a build target. For sdk
and program, also configure the features to be enabled.
