ShellPkg/UefiShellDebug1CommandsLib: Replace hardcoded SMBIOS strings.
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3805
Replace hardcoded SMBIOS Anchor string and size with defines.
Fix buffer overflow as described below.
Smbios64BitPrintEPSInfo () is coded like:
UINT8 Anchor[5];
MemToString (Anchor, SmbiosTable->AnchorString, 5);
But the definition of MemToString()
Copy Length of Src buffer to Dest buffer,
add a NULL termination to Dest buffer.
So Anchor needs to be +1 the size of the SMBIOS Anchor string `_SM3_`.
Changes from v1 to v2:
- Replace doxygen style inline comments
