mm: Kconfig: simplify zswap configuration
- CONFIG_ZRAM: Zram is a user-facing feature, whereas zsmalloc is
not. Don't make the user chase down a technical dependency like
that, just select it in automatically when zram is requested. The
CONFIG_CRYPTO dependency is redundant due to more specific deps.
- CONFIG_ZPOOL: This is not a user-facing feature. Hide the symbol and
have it selected in as needed.
- CONFIG_ZSWAP: Select CRYPTO instead of depend. Common pattern.
- Make the ZSWAP suboptions and their descriptions (compression,
allocation backend) a bit more straight-forward for the user.
