Infer filter as a mixed readonly array method

[raashish1601]

Summary

• infer .filter property loads as the MixedReadonly array method shape
• preserve the existing noAlias callback behavior for untyped props arrays using .filter
• add a regression fixture for local mutation inside a filter callback in useMemo

Why

When items comes from untyped props, items.filter was inferred as a generic function, so the local-mutation validator treated the callback as potentially escaping through the filtered result. The MixedReadonly model already defines .filter as a built-in array method with noAlias; this change lets that model apply to .filter property loads from untyped values.

Fixes #31569.

Test Plan

• corepack yarn workspace snap run snap --update --pattern local-mutation-in-filter-usememo --sync
• corepack yarn workspace snap run snap --pattern local-mutation-in-filter-usememo --sync
• corepack yarn workspace babel-plugin-react-compiler run lint -- --quiet
• corepack yarn prettier

Note: corepack yarn workspace snap run snap --pattern "{local-mutation-in-filter-usememo,noAlias-filter-on-array-prop}" --sync showed the new fixture passing; noAlias-filter-on-array-prop only failed on CRLF/LF snapshot text in this Windows checkout with identical generated code.
