Option to Upload PageBlobs to BlockBlobStorage and BlobStorage Accounts

[jcrobins]

Storage Explorer Version: 1.6.2
Platform/OS Version: Windows
Architecture: ia32
Regression From: N/A

Steps to Reproduce:

1. Create a Premium BlockBlobStorage (or Standard BlobStorage) storage account.
2. Select the created storage account in Storage Explorer.
3. Select a container in this account in Storage Explorer and select Upload > Upload Files... to view the Microsoft Azure Storage Explorer - Upload Files to Blob Container dialog.

Expected Experience:

Page Blob should not be a selectable option in the Blob type drop-down.
The "Upload .vhd/vhdx files as page blobs (recommended)" checkbox should not be available.

Actual Experience:

Page Blobs are a selectable option in the Blob type drop-down.
The "Upload .vhd/vhdx files as page blobs (recommended)" checkbox is available.

Essentially a duplicate of #1171. Simply asking for upload dialog to not offer blob types that won't work with the current Storage Account type.
