[MGT React] Export mgt types imported in generated.ts

[nmetulev]

Description

mgt-react should export types used by mgt-react components

Rationale

Today, the developer is required to import from both @microsoft/mgt and @microsoft/mgt-react. This proposal would allow the types to be re-exported from mgt-react so only one import statement is needed for most scenarios.

Preferred solution

Update the generator code to add an export statement at the end for the same types that are imported at the top.
