normalizes exchange api naming and client usage.
Also moves serialization and transformation to and from graph client objects out of graph/support and into the api. Some parts of graph/support have been moved into conn/ exchange instead, since they're more oriented around certain forms of object consumption rather than broad object serialization.
Except for different uses of api client graph servicers, all changes are movement/renaming.

now that exchange api has been folded in with the rest of the m365 api, it doesn't make sense to maintain an options file with only exchange functionality. Since all calls in the file were used 1:1 with some api func, those options have been moved into their respective api funcs.

No logic changes, just code movement.
Begins the process ofcentralizing the graph package in pkg/services/m365, instead of dividing up the funcs between different connector subpackages. While the ownership of apis in each connector subpackage does make sense, this movement will reduce duplication, centralize import arrangements, and make it easy
to export usage of the api to sdk consumers.

Instead of returning `Info` in `User`, callers should call the `GetUserInfo` API to get extended user information.
This allows the caller to decide whether info is needed *and* control parallelism for these queries.
This change introduces a `UserCompatNoInfo` call that allows us to make the switch without breaking existing `UserCompat` references. We will remove this API after callers have switched.

A few high-level things of note:
* things will no longer match on folder ID. Folder IDs weren't displayed
to the user via CLI and SDK consumers have no insight into folder IDs
so this shouldn't be an issue
* OneDrive and SharePoint match on ParentPath (derived from
LocationRef). ParentPath *does not* include root: in the path
Not matching on folder ID should be the only user-visible change in
this PR
First commit contains the required logic changes. All other changes
are test updates
