This reverts commit e61f485a, reversing
changes made to 00c47d07.

The folder where the disk cache lives was originally renamed from llvfs to llcache but @henri's suggestion that that doesn't reflect the other files in the same place and it should be llfilesystem is a good one so I changed it over

First part of change to remove LLVFS from the Viewer. Consists of code changes to remove LLVFS and LLVFSThread classes along with the associated source files. The existing llvfs folder is renamed to llcache. Also includes changes to CMake script in many places to reflect changes. Eventually, llvfile source file and class will be renamed but that is not in this change.

The LLDir base class method will now be used instead. The handling of the mask
parameter was inconsistent between the two implementations, and the failure
to remove the old method was probably just an oversight.

Not related, just a while-I'm-at-it thing.

As far as I know, there is no good reason to include e.g.
indra/llvfs/lldir_win32.h while not building for a windows target, so be
better prevent this to avoid hard to find errors.

- Replaced all existing usages of LLDir::getNextFileInDir() with the new directory iterator object.
- Removed platform specific LLDir::getNextFileInDir() implementation.

Some branch shenannigans in the pluginapi_05 branch caused this to become a two-part merge.
