refactor(scoop-shim): Use getopt to parse arguments

[lewis-yeung]

Description

Use getopt to parse arguments, which avoids some problems. BTW, add some logic and tweak some error messages.

Motivation and Context

These problems will be resolved:

1. For example, run scoop shim add myapp '', the second parameter (<command_path>) gets an empty value, so Scoop will throw an exception, which is not so friendly. :

   Cannot validate argument on parameter 'Name'. The argument is null or empty. Provide an argument that is not null or empty, and then try the command again.
   

2. For example, run scoop shim list *, the regex pattern * is invalid, so Scoop will throw an exception, which is not so friendly. :

   Invalid pattern '*' at offset 1. Quantifier {x,y} following nothing.
   

3. The -g/--global option cannot be parsed in scoop shim .... See [Bug]scoop shim info : ERROR: Option -global not recognized. #5094.

How Has This Been Tested?

Now with this:

1. scoop shim add myapp '' shows an error:

   ERROR <command_path> must be specified for subcommand 'add'
   

2. scoop shim list * shows an error:

   ERROR: Invalid pattern: *
   

3. To create a local shim myapp with arg and --global as arguments:

   scoop shim add myapp 'D:\path\myapp.exe' '--' arg --global

   Note that we have to use a QUOTED command option terminator ('--') in PowerShell CLI.

4. To create a global shim myapp with arg as the argument:

   scoop shim add -g myapp 'D:\path\myapp.exe' arg

No major changes to other subcommands.
