MdePkg: Add DEBUG_SECURITY Bit in PcdDebugPrintErrorLevel
Tcg2Dxe and its libraries are currently the noisiest modules in
edk2. For a sample platform printing at INFO level, Tcg2Dxe
printed 4,000 lines out of 5,700 total lines printed.
This commit defines a DEBUG_SECURITY bit to control the debug output
of Tcg2Dxe and other security related components. Most of the output is
not useful except for deep debugging of TPM transactions, so it is
appropriate to only print when the DEBUG_SECURITY bit is present.
