StdLib/LibC: Add software floating point library from NetBSD
Floating point processing is not supported on ARM for UEFI. In order to
support UEFI applications in AppPkg we use this library to provide the
required functionality.
Changes as compared to the NetBSD version:
- Formatting changes (tabs to spaces, DOS line endings etc).
- Disable exceptions as described in the float_raise() function.
- Disable definition of 'Symbolic Boolean literals' in milieu.h.
