Move @uifabric packages under @fluentui scope

[ecraig12345]

Part 3/4 in a series of changes that must happen in master after v7 development moves to a branch, but before beta publishing:

1. Merge OUFR and react-next into react #15152 OUFR/react-next merge
2. Re-export date-time components from react #14679 Move date-time components
3. (this) Move @uifabric packages under @fluentui scope #13384 uifabric/fluentui package renames
4. Set up beta releases #14689 set up beta releases

As part of version 8, we'd like to rename our @uifabric packages to @fluentui (or in a few cases, delete unneeded packages going forward).

For packages which are used by the suite, we'll add @uifabric aliases (which re-export the @fluentui version) so that partners who depend on multiple suite versions won't get multiple versions of all the dependency packages. (Creation of the alias packages will be done at a slightly later point after the renames, but before release--tracked by #15150.)

EDIT: Trying to handle package renames and getting rid of major-lockstep at the same time turned out to be too complex, so we will be continuing with major-lockstep for now and NOT making any alias packages. However, we will likely provide a codemod to help with renames (see #15661).

In some cases, we're changing the names of the @fluentui versions of the packages to better match current naming conventions, or to reserve @fluentui names for future use.

Rename script
