doc: Add anchors to long lists

Added using the following sed scripts:

- For command-ref/opt-common.md:

    s~- `(--?)([^`]+)`~- [`\1\2`]{#opt-\2}~g

- For expressions/builtin-constants.md:

    s~- `(builtins\.?)([^`]+)`~- [`\1\2`]{#builtins-\2}~g

- For expressions/advanced-attributes.md

    s~^  - `([^`]+)`~  - [`\1`]{#adv-attr-\1}~g

  and manually adjusted outputHashAlgo & outputHashMode.

- For glossary.md

    s~^  - (`([^`]+)`|(.+)) ?\\~  - [\1]{#gloss-\2\3}\\~g;
    s~(gloss-\w+) ~\1-~g

  and manually adjusted anchors for Nix expression, user environment, NAR, ∅ and ε.

- For command-ref/env-common.md

    s~^  - `([^`]+)`~  - [`\1`]{#env-\1}~g'
