[Storage] Integrate XSCL v12 to Storage module, to support new storage features

[blueww]

Description

Reopen on new storage preview branch as #11177 is closed.

There are no syntax changes, so no review docs raised in https://github.com/Azure/azure-powershell-cmdlet-review-pr

But I have raised a design doc, Erich has helped to review it. https://microsoft.sharepoint.com/:w:/t/XClientShanghai/EVNIP90Ijg1KsZT0VFEA6pgB33mx1WbdypGOXWTkLvgTHA?e=7SjutU

For Oauth:

For the oauth token, I implement my own class "AzureSessionCredential", I can switch to the common one provided by Powershell team (prototype： https://github.com/erich-wang/azure-powershell/commit/2b3791333) when it's merged to master.

Commits:

This PR include many changes from master, which is not already on storage branch.
Only the last commit is for this feature change.
When #11161 is merged, should only left the last commit.

For test:

I have tested it works on

• Powershell 5.1
• Powershell 6.2.4

With authentication:

1. Key
2. SAS
3. Oauth
4. Anonymous

@erich-wang Hi Erich, could you review this PR cause it's related to track 2 SDK? Thanks

BTW @blueww I'm not sure but it could be that the static analysis error was caused by wrong format of L59-60 in https://github.com/Azure/azure-powershell/blob/Az.Storage-preview/tools/StaticAnalysis/Exceptions/Az.Storage/SignatureIssues.csv#L59

@isra-fel

@erich-wang has a fix for the static analysis issue in https://github.com/Azure/azure-powershell/tree/erich/storage-track2-analysis
But the fix is still not finalized, and still need discuss with Mark.
