[Portal] Re-export 'Portal' in material

[liradb2000]

Recently #30853 is pushed and applied version 5.4.x.

However, Portal Component is missing and can't access the component.

In #30853 PR,

Note: utility components, such as ClickAwayListener, NoSsr, Portal, and TextareaAutosize continue to be exported from both @mui/material and @mui/base

This PR is a re-export Portal Component and can access the Component without '@mui/base' package.

// package/mui-material/src/index.js
...
export * from './Popper';

+ export { default as Portal } from './Portal';
+ export * from './Portal';
+
export { default as Radio } from './Radio';
...

// package/mui-material/src/index.d.ts
...
export * from './Popper';

+ export { default as Portal } from './Portal';
+ export * from './Portal';
+
export { default as Radio } from './Radio';
...
