chore: restructure shared and react to use /core package

[yeager-eren]

Summary

Update all imports from core to import from core/legacy and move some functionality from /shared to /core.

In long term we will remove wallets-shared, a part of this PR is moving core-related functionality to wallets-ocre. And also this PR prefixed all the legacy core with legacyThenSomething to make sure we are flagging them and give a notice they are deprecated and will be removed in next major version.

Aliasing

In those packages who imported types or functions from legacy code, you will see I'm aliasing the legacySomething to legacySomething as something, this is because I wanted to update only imports and not the usages. I believe this is more appropriate way to reduce the changes.

core/legacy/package.json

module system other than node16 and bundler doesn't have support for package.json's exports field. For backward-compatibility reasons we needed a workaround. I checked some repositories and all of them used the way thar I used in this PR. here is an example.

How did you test this change?

It shouldn't have any side effect on user side. it can affect our building process. so make sure the project will be build correctly.
