Case-insensitive parsing of metadata properties actorStateStore and keyPrefix

[ItalyPaleAle]

In components-contrib, we've been making some efforts to make all component metadata parsing case-insensitive (thanks especially to @berndverst ) and use utils.IsTruthy to parse booleans.

The runtime itself parses the component metadata to extract certain fields, including: actorStateStore (state stores) and keyPrefix (state stores and locks).

This PR changes matching for actorStateStore and keyPrefix to be case-insensitive. Additionally, it uses utils.IsTruthy to convert actorStateStore to a boolean (so it's case-insensitive too and values like "1" map to true).

Also includes some fixes to pkg/components/lock/lock_config.go that were applied in pkg/components/state/state_config.go (whose code looks almost identical and perhaps should be merged into a single file)
