dev-lang/parrot: -r1 bump for EAPI7

Looks like no new releases are happening in the near future, so
bumping the last release by one -r step for EAPI7 conversion

- All use of "|| die" removed from builtins (these have auto-died'
  since EAPI4 )
- Rework doc handling logic to avoid use of banned "dohtml"
- Stripped auxilliary copies of docs in "docs/${PF}/parrot/${PV}"
- Remove excess indirection of "doc/${PF}/editor/editor"
- Unified docs, examples, and html handling with "einstalldocs"
