feat: bump c-kzg, add portable feature, make it default

[Rjected]

This uses the new portable feature, enabled by default, for c-kzg. Also bumps c-kzg version. Removes the need to do:

// TODO: remove when we have `portable` feature in `c-kzg`
use blst as _;

and

# TODO: remove `blst` dep when `c-kzg` has a portable feature
c-kzg = ["dep:c-kzg", "revm-primitives/c-kzg", "dep:blst", "blst?/portable"]
