Move export of Global ID to Guid and export Global ID field

[MikeMillerGIS]

We found that we can load a field of type of GUID to Global ID, if the Target has a Unique index and the GUID field in the file gdb has Unique index.

I propose we expose the Global ID field in the source to target dialog. We always convert Global ID to a GUID field in the export.

this will help when we are using a layer with a join

One solution could be

1. Build a GUID field in the intermediate data (some arbitrary unique field name)
2. Copy globalid field from source into the new GUID field
3. Use this GUID field in lieu of original source globalid field.
4. Repeat for all source globalid fields (Possible with a join layer in 2.x)

That is what I was thinking
