BaseTools: Rename AmlToHex script to AmlToC

The AmlToHex script and Posix/WindowsLike wrappers convert
an AML file to a .hex file, containing a C array storing
AML bytecode. This ".hex" file can then be included in a
C file, allowing to access the AML bytecode from this C
file.

The EDK2 build system doesn't allow to a depict dependency
orders between files of different languages. For instance,
in a module containing a ".c" file and a ".asl", the ".c"
file may or may not be built prior to the ".asl" file.
This prevents any inclusion of a generated ".hex" in a
".c" file since this later ".hex" file may or may not
have been created yet.

This patch renames the script as AmlToC. It is posted as
a separate patch to prevent git from seeing the renaming
as a deletion plus addition of a new file.
The ending line of the posix-like bin-wrapper script has
also been corrected.

This is a first step toward generating a C file containing
the AML bytecode from an ASL file. This C file will then
be handled by the EDK2 build system to generate an object
file.
Thus, no file inclusion will be required anymore. The C file
requiring the AML bytecode as a C array, and the ASL file,
will be compiled independently. The C array must be defined
as an external symbol. The linker is resolving the
reference to the C array symbol.

To summarize, the flow goes as:
 -1. ASL file is compiled to AML;
 -2. AML file is copied to a ".amli" intermediate file;
 -3. EDK2 build system applies the rule relevant to ".amli"
     files. This is, calling the "AmlToC" script, generating
     a C file from the ".amli" file;
 -4. EDK2 build system applies the rule relevant to C files.
     This is creating an object file.
 -5. EDK2 build system links the object file containing the
     AML bytecode with the object file requiring it.
