This patch makes Shell support -nonesting invocation option. This option
specifies that EFI_SHELL_PROTOCOL.Execute API nesting of a new Shell
instance is optional and dependent on the 'nonesting' Shell environment
variable.

When the FvSimpleFileSystemDxe module is included in a platform,
Simple File System Protocols are produced for firmware volumes(FV)
that do not have the same style device paths as file systems with
file names. The ShellPkg has an assumption that the device path
contains device path nodes of type MEDIA_FILEPATH_DP and generates
an ASSERT() if any other device path nodes are encountered. This
change removes the ASSERT() condition and instead returns NULL that
means EfiShellGetFilePathFromDevicePath() can not convert the
device path nodes that represent the file path to a Unicode string.

1. Add a new function 'RunShellCommand' to return command status, thus 'EfiShellExecute' can get the command return status of 'CommandLine'.
2. Refine the code logic of 'EfiShellExecute' to make the new image of shell be loaded only if 'Environment' isn't NULL.

In Shell spec 2.1 the return name of EFI_SHELL_PROTOCOL.GetCurDir() is defined as 'fs0:\current-dir' while in current implementation it's 'fs0:\current-dir\'.
To follow spec the patch removed the redundant '\' char.
Since it has been broken for a long time, some codes may depend on the broken behavior.
After this change 'EFI_SHELL_PROTOCOL.GetCurDir()' and 'UefiShellLib.ShellGetCurrentDir()'
will return a current directory string without tailing '\' (fs0:\current-dir), the value of Shell environment variable 'cwd' will become 'fs0:\current-dir' as well.
This patch has updated all the code in EDKII to make them depend on the new behavior.
Developers should check whether 'GetCurDir()' and 'ShellGetCurrentDir' are used in their source code.

CurrentFilePattern is only part of FilePattern and will be less than or equal to FilePattern. If we use StrCpyS to replace StrnCpy, it will cause assert when FilePattern is longer.
The bug can be replayed when we cd to one directory and run ls command.

The function InternalShellExecuteDevicePath() did not differentiate an error occuring during the preparation of an image and an error occurring during its execution.
A use case of the issue was when a EFI application was called in a EFI Shell script. If the EFI application was returning an error then the NSH script stopped its execution. While the EFI Shell specification says the script should continue its execution (see 4.2 Error Handling).
