81e7c40264 Optimize primop calls 
We now parse function applications as a vector of arguments rather
than as a chain of binary applications, e.g. 'substring 1 2 "foo"' is
parsed as

  ExprCall { .fun = <substring>, .args = [ <1>, <2>, <"foo"> ] }

rather than

  ExprApp (ExprApp (ExprApp <substring> <1>) <2>) <"foo">

This allows primops to be called immediately (if enough arguments are
supplied) without having to allocate intermediate tPrimOpApp values.

On

  $ nix-instantiate --dry-run '<nixpkgs/nixos/release-combined.nix>' -A nixos.tests.simple.x86_64-linux

this gives a substantial performance improvement:

  user CPU time:      median =      0.9209  mean =      0.9218  stddev =      0.0073  min =      0.9086  max =      0.9340  [rejected, p=0.00000, Δ=-0.21433±0.00677]
  elapsed time:       median =      1.0585  mean =      1.0584  stddev =      0.0024  min =      1.0523  max =      1.0623  [rejected, p=0.00000, Δ=-0.20594±0.00236]

because it reduces the number of tPrimOpApp allocations from 551990 to
42534 (i.e. only small minority of primop calls are partially
applied) which in turn reduces time spent in the garbage collector.

Reword "we"s to "I"s for consistency 
This script uses multiple forms of the first-person POV:
1. "We" to refer to the Nix team (1e7c796e66/scripts/install-multi-user.sh (L72))
2. "We" to refer to the combination of the installation script & the user/executor (1e7c796e66/scripts/install-multi-user.sh (L710))
3. "We" to refer to the installation script alone (1e7c796e66/scripts/install-multi-user.sh (L602))
4. "I" to refer to the installation script alone (1e7c796e66/scripts/install-multi-user.sh (L200))

Since I prefer POV 4 to POV 3, this changes all instances of POV 3 to POV 4.

447350fe0e installer: Do not use echo -e in #!/bin/sh script 
ShellCheck correctly warns:

In scripts/install-nix-from-closure.sh line 218:
                echo -e "\nif [ -e $p ]; then . $p; fi # added by Nix installer" >> "$fn"
                     ^-- SC3037: In POSIX sh, echo flags are undefined.

In scripts/install-nix-from-closure.sh line 229:
                echo -e "\nif [ -e $p ]; then . $p; fi # added by Nix installer" >> "$fn"
                     ^-- SC3037: In POSIX sh, echo flags are undefined.

Indeed, this actually breaks on Ubuntu where /bin/sh is dash.

Fixes #5458.

af99941279 Make experimental-features a proper type 
Rather than having them plain strings scattered through the whole
codebase, create an enum containing all the known experimental features.

This means that
- Nix can now `warn` when an unkwown experimental feature is passed
  (making it much nicer to spot typos and spot deprecated features)
- It’s now easy to remove a feature altogether (once the feature isn’t
  experimental anymore or is dropped) by just removing the field for the
  enum and letting the compiler point us to all the now invalid usages
  of it.

- PoC: `let x = builtins.fetchurl x; in x`
- Before:
  ```bash
