Alex Dale d7eab65c8c Fixed dangling pointer issue in CdmInfo.

[ Cherry-pick of http://ag/34331848 ]
[ Merge of http://go/wvgerrit/224951 ]

There was a potential dangling pointer issue that was enabled
by how CdmInfo is initilized.  The file system that was passed
into the CdmEngine instance was pointing to a location in memory
that was not stable between move operations in the CdmInfo.
See b/429054262 for memory diagram of issue.

The CdmInfo is a private class within the Android CDM class, which
restricts the potential operations on it.  The easiest solution
is wrap the file system in a unique pointer; ensuring the pointer
remains stable even if a particular data segment of CdmInfo is
moved.

The default constructor for CdmInfo is deleted; this will force the
compiler to fail if |cdms_| is used in ways that would result in
uninitialized pointers.

Bug: 429054262
Test: WvTs on Komodo

README

This is the source code for the Widevine Content Decryption Module (CDM) for the
Android OS.  It provides the libwvdrmengine plugin for DRM.

Partners who are integrating a device should be familiar with the documents in
the docs directory.

This source code is NOT open source, and is not part of AOSP.  However, it is
released to partners external to Google after official Android releases.  For
this reason, partners should look for bug fixes and software updates on the
widevine branches:
