Revert "rust deps: bump crypto/encoding"

What

This MR reverts commits upgrading Kernel SDK, Etherlink, and other kernels to use Tezedge v0.6.0.

Why

The recent upgrade causes float point instruction errors in WASM PVM and the fastest way to bring master back to operational state is to revert related changes.

How

Revert all commits from !13965 (merged)

Manually testing the MR

Install necessary deps

cd etherlink/kernel_evm/benchmarks
npm i

In the repo root

make
make -f etherlink.mk EVM_KERNEL_FEATURES=debug evm_benchmark_kernel.wasm
node etherlink/kernel_evm/benchmarks/scripts/run_benchmarks.js -o /tmp/

If benchmark scripts are running without errors, everything is OK.

Alternatively (in the project root)

make -f etherlink.mk EVM_KERNEL_FEATURES=debug evm_benchmark_kernel.wasm
wasm2wat evm_benchmark_kernel.wasm -o kernel.wat
grep -nE 'f(32|64)\.' kernel.wat 

If there are no f32/f64 instructions then everything is fine (there might be f64 in the function names e.g. soft_f64 but that's ok).

There is also a new CI check: !14144 (merged)
