Subject: [PATCH v3 15/17] crypto: Kconfig - simplify userspace entries

Shorten menu titles and make them consistent:
- acronym
- name
- architecture features in parenthesis
- no suffixes like "<something> algorithm", "support", or
  "hardware acceleration", or "optimized"

Simplify help text descriptions, update references, and ensure that
https references are still valid.
