Write name and value for each env var

In order to res0lve https://github.com/rust-lang/miri/issues/756 is necessary to have the whole `"NAME=VALUE"` sequence of bytes written into memory instead of just the value.

This change does not affect the interface of the `shim::envs::EnvVars` type in any way.

don't call Memory::get without checking the pointer first

Also avoid Memory::get if we just need to know align/size.

I audited all uses of `alloc_id`; the rest should be fine (and we can kill a bunch of them once https://github.com/rust-lang/rust/pull/62257 lands).
