Fix various errors when piping a UNICODE or ASCII file to a simple shell application that reads standard input and writes it to standard output.
1) When the memory file is created by CreateFileInferfaceMem() to capture the pipe output, no UNICODE BOM is written to the memory file. Later, when the memory file is read by the application using ShellFileHandleReadLine(), the function indicates that the file is ASCII because there is no BOM.
2) If the file is piped as ASCII, the ASCII memory image is not correctly created by FileInterfaceMemWrite() as each ASCII character is followed by '\0' in the image (when the ASCII data is written to the memory image, the file position should only be incremented by half the buffer size).
3) ShellFileHandleReadLine() does not read ASCII files correctly (writes to Buffer need to be cast as CHAR8*).
4) FileInterfaceMemRead() and FileInterfaceMemWrite() as somewhat hard to read and difficult to debug with certain tools due to the typecasting of This. Added a local variable (MemFile) of the correct type to these functions and used it instead of This.
Enhancement: ShellFileHandleReadLine() now returns EFI_END_OF_FILE when appropriate.

SVN r16601 ("MdeModulePkg, MdePkg, NetworkPkg, OvmfPkg, PerformancePkg,
ShellPkg: Library Migration.") incorporated ShellPkg/Library/BasePathLib
into MdePkg/Library/BaseLib. BasePathLib had been the only instance of
library class PathLib.
Even so, SVN r16606 ("ShellPkg: allow creating of files to create required
directory path") added a PathLib dependency to
"ShellPkg/Library/UefiShellLib/UefiShellLib.inf".
This breaks edk2 platforms that build the "new" UEFI shell from source.
Undo the wrong dependency.
Similarly, update the <Library/PathLib.h> #include directive to
<Library/BaseLib.h> (example function prototype: PathRemoveLastItem()).

Shell Libraries can now be used from Platform Drivers with the
introduction of the Shell Dynamic Command Protocol.
Adding DXE_DRIVER class allows to use these libraries with this
class of driver.
