OsLoader - Container Type Cleanup (#1816) 
* Add Name field to IMAGE_DATA structure

Add a name field to the structure to be used by container parsing
functions. It will be useful to determine the name of the container
component when dealing with special files like ACPI blobs.

* OsLoader: save the name of the component when creating array of components

Saving the name will help us deal with special files like ACPI blobs
more easily

* OsLoader: streamline container types

Update container functionality to streamline container types:
- Normal: PE32, FV, ELF images. Supports ACPI table update.
- Classic (Linux): Used for a traditional Linux boot setup.
  (cmdline, bzImage, initrd). Additionally supports ACPI table update.
- Multiboot: Used for Multiboot/Multiboot-2 compliant ELF images.
  Supports ACPI table update.

* Rename CLASSIC container to CLASSIC_LINUX

This type of container is to be used for a traditional Linux
boot setup consisting of a cmdline, bzImage, initrd(optional),
and other binary blobs or ACPI blobs.

Rename it to CLASSIC_LINUX to make the purpose of the container
clearer.

* OsLoader: copy Linux ExtraBlobs to reserved mem and add to cmdline

Until now, SBL loaded the Extra blobs with the Linux kernel
into memory. However, there was no way for the OS to know where
these blobs resided in memory. The blobs were also loaded in
memory that was not marked as reserved.

This patch copies the blobs to reserved memory and adds the
blob addresses into an expected placeholder in the Linux cmdline.
If the placeholder is not present, nothing related to that blob
will be added to the cmdline.

Slim Bootloader
================

**Welcome to the Slim Bootloader project!**

Slim Bootloader is an open-source boot firmware solution, built from the
ground up to be secure, lightweight, and highly optimized while leveraging
robust tools and libraries from the [EDK II](https://www.tianocore.org/edk2/)
framework.

What is a Bootloader?
---------------------
Just like a typical [BIOS](https://en.wikipedia.org/wiki/BIOS), Slim Bootloader
is the piece of software responsible for initializing the core hardware
components of the system when it is powered on, followed by the loading and
launching of the desired operating system.

Slim Bootloader offers the flexibility for OEMs, device manufacturers, and hobbyists
to isolate, configure, and optimize for the the specific requirements of the system
thereby achieving unparalleled boot performance and minimizing firmware footprint.

Supported Platforms
-------------------
Please visit [Supported Hardware](https://slimbootloader.github.io/supported-hardware/index.html) page for a list of platforms supported by Slim Bootloader.
