The `WP_Block_Parser` class, and the accompanying `parse_blocks()` helper function, can be used to parse an array of blocks out of a content string.
`WP_Block_Parser` is copied from the `@wordpress/block-serialization-default-parser` package. To ensure it stays in sync with the JavaScript parser, changes should be implemented in the package first, then the package version should be upgraded to include the changes.

These are the foundational classes allowing blocks to be registered and used throughout WordPress.
This commit also includes the `has_block()` and `has_blocks()` functions, which are required for unit testing these classes.
