Gua Guo 9a75b030cf StandaloneMmPkg/Hob: Integer Overflow in CreateHob()
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4166

Fix integer overflow in various CreateHob instances.
Fixes: CVE-2022-36765

The CreateHob() function aligns the requested size to 8
performing the following operation:
```
HobLength = (UINT16)((HobLength + 0x7) & (~0x7));
```

No checks are performed to ensure this value doesn't
overflow, and could lead to CreateHob() returning a smaller
HOB than requested, which could lead to OOB HOB accesses.

Supreeth Venkatesh 70a51d7187 StandaloneMmPkg/HobLib: Add HOB Library for management mode.
The Standalone MM environment is initialized during the SEC phase on ARM
Standard Platforms. The MM Core driver implements an entry point module
which is architecture specific and runs prior to the generic core driver
code. The former creates a Hob list that the latter consumes. This
happens in the same phase.

This patch implements a Hob library that can be used by the entry point
module to produce a Hob list and by the core driver code to consume it.
