Add nasm for Windows cross-compile builds (#39)

Fixes the 32-bit Windows cross-compile build failure caused by missing
`nasm`.

## Problem

The `aws-lc-sys` crate (pulled in via `openssl` -> `rustls`) requires
`nasm` for assembling optimized cryptographic routines on x86 targets.
The CI workflow installed `gcc-mingw-w64` for Windows cross-compilation
but not `nasm`, causing builds to fail with: `NASM command not found!
Build cannot continue.`

## Fix

Add `nasm` to the `apt install` in the Windows build dependencies step.
