Move permission schema metadata into 7715 permission types

[mj-kiwi]

📝 Description

Moves shared ERC-7715 permission schema metadata into @metamask/7715-permission-types.

🔄 What Changed?

List the specific changes made:

• Added permission schema types, schema registry, constants, and pure schema utilities to @metamask/7715-permission-types
• Added MetaMask facilitator address grouping helpers
• Exported the schema API from the package root and permissions module
• Added tests for schema lookup and facilitator address matching

🚀 Why?

Explain the motivation behind these changes:

• Allows MetaMask Extension to consume shared permission schema definitions from the package
• Keeps rendering/UI behavior in extension while centralizing reusable permission metadata

• Manual testing steps:

1. yarn workspace @metamask/7715-permission-types test
2. yarn workspace @metamask/7715-permission-types build

📚 Additional Notes

Rendering remains in MetaMask Extension; this PR only moves shared schema metadata and pure helpers.

Note

Low Risk
Additive package API and declarative metadata only; no runtime permission enforcement changes, with tests for schema lookup edge cases.

Overview
Adds a new permissions/schema module to @metamask/7715-permission-types so MetaMask Extension (and other consumers) can share declarative metadata for Gator permission confirmation/review UI instead of duplicating it locally.

The module defines schema types (PermissionRenderContext, field elements, sections), a registry for supported types (native/ERC20 periodic, stream, allowance, token-approval-revocation), and getPermissionSchemaEntry with an unknown-type fallback and optional strict mode. Schemas describe which fields appear in confirmation, reviewDetail, and reviewSummary, including redeemer/payee display logic that treats known MetaMask facilitator addresses specially.

Also ships pure helpers: time/MAX_UINT256 constants, hex amount parsing, period/frequency i18n keys, stream rate conversions, and isMetaMaskFacilitatorAddress / areOnlyMetaMaskFacilitatorAddresses. The API is re-exported from the package root and permissions index; changelog and unit tests cover lookup, __proto__ safety, and facilitator matching.
