MdeModulePkg: Add two library instances
Copy below two library instances from IntelFrameworkModulePkg to MdeModulePkg. Then, Platform dsc can
refer to them from MdeModulePkg, and remove the dependency of IntelFrameworkModulePkg. The ones in
IntelFrameworkModulePkg are still kept for compatibility.

+These functions convert relative addresses to absolute addresses
+in CALL instructions to increase the compression ratio.
+
+ In:
+ data - data buffer
+ size - size of data
+ ip - current virtual Instruction Pinter (IP) value
+ state - state variable for x86 converter
+ encoding - 0 (for decoding), 1 (for encoding)
+
+ Out:
+ state - state variable for x86 converter
+
+ Returns:
+ The number of processed bytes. If you call these functions with multiple calls,
+ you must start next call with first byte after block of processed bytes.
+
+ Type Endian Alignment LookAhead
+
+ x86 little 1 4
+ ARMT little 2 2
+ ARM little 4 0
+ PPC big 4 0
+ SPARC big 4 0
+ IA64 little 16 0
+
+ size must be >= Alignment + LookAhead, if it's not last block.
+ If (size < Alignment + LookAhead), converter returns 0.
+
+ Example:
+
+ UInt32 ip = 0;
+ for ()
+ {
+ ; size must be >= Alignment + LookAhead, if it's not last block
+ SizeT processed = Convert(data, size, ip, 1);
+ data += processed;
