Add cscopeOverwritePath setting

The ability to overwrite the path to the cscope
executable is needed to support custom installations.

- Added a new setting, `edk2code.cscopeOverwritePath`, to allow users to
  specify a custom path to the cscope executable.
- Modified the `Cscope` class constructor to use the value of
  `cscopeOverwritePath` if provided, otherwise it falls back to the
  default behavior.
