fix: Remove HTMLElement constraint for React Native compatibility (#1065)

* Fix: Remove HTMLElement constraint for React Native compatibility

Fixes #1051

Changes:
- Remove 'T extends HTMLElement' constraint from FieldInputProps, FieldRenderProps, and FieldProps
- Change to 'T = any' to support both React DOM and React Native
- Re-export FieldMetaState type for backwards compatibility (was removed in v7.0.0)

This allows React Native users to use react-final-form without TypeScript errors
while maintaining full backwards compatibility with React DOM users.

* fix: Update TypeScript declarations to match React Native type changes

- Change generic constraint from 'T extends HTMLElement = HTMLElement' to 'T = any'
- Add FieldMetaState type export for backwards compatibility
- Sync all type declarations with src/types.ts changes

* docs: Clarify FieldMetaState comment per CodeRabbit feedback

Changed comment from '(removed in v7.0.0)' which reads like a future
removal, to clarify it was removed from sources but re-exported here for
backwards compatibility.
