Rollup merge of #127860 - klensy:dedup, r=Mark-Simulacrum

deps: dedup object, wasmparser, wasm-encoder

* dedups one `object`, additional dupe will be removed, with next `thorin-dwp` update
* `wasmparser` pinned to minor versions, so full merge isn't possible
* same with `wasm-encoder`

Turned off some features for `wasmparser` (see features https://github.com/bytecodealliance/wasm-tools/blob/v1.208.1/crates/wasmparser/Cargo.toml) in `run-make-support`, looks working?
