Fixes https://github.com/payloadcms/payload/issues/10940
This PR does the following:
- adds a `useDocumentForm` hook to access the document Form. Useful if
you are within a sub-Form
- ensure the `data` property passed to field conditions, read access
control, validation and filterOptions is always the top-level document
data. Previously, for fields within lexical blocks/links/upload, this
incorrectly was the lexical block-level data.
- adds a `blockData` property to hooks, field conditions,
read/update/create field access control, validation and filterOptions
for all fields. This allows you to access the data of the nearest parent
block, which is especially useful for lexical sub-fields. Users that
were previously depending on the incorrect behavior of the `data`
property in order to access the data of the lexical block can now switch
to the new `blockData` property
