Remove code which loads legacy libolm

Browse source 
Now that we use the Rust crypto stack
(https://github.com/matrix-org/matrix-react-sdk/pull/12630), the legacy olm
library is unneeded. Remove all the dedicated cruft for loading it.

(All this crap is why matrix-sdk-crypto-wasm has to base64 its wasm artifact,
cf https://github.com/matrix-org/matrix-rust-sdk/pull/1167.)
