Add BuiltInCapabilities() to x/wasm/keeper and deprecate AllCapabilities()

[webmaster128]

AllCapabilities() is currently used by chains

1. without additions (https://github.com/cosmos/gaia/pull/3051/files#diff-1ac782d2fab1d48ad7f7ef06cf2d58b37c99b6b4c98879a5ad86a985b73fad58R456)
2. with additions (https://github.com/CosmosContracts/juno/blob/e98863bf7112f4b117a2114e22f7482367362764/app/keepers/keepers.go#L114)

This is good since it avoids bugs and adds newly added capabilities autimatically in an upgrade.

This PR does not change functionality but improves things in the following ways:

• Better documentation
• Better function name
• As Pino highlighted, the symbols from app should not be imported by chains using x/wasm
