bswap.h: define GIT_LITTLE_ENDIAN on msvc as little endian
The Microsoft Visual C++ (MSVC) compiler (as of Visual Studio 2022
version 17.13.6) does not define __BYTE_ORDER__ and its C-library does
not define __BYTE_ORDER. The compiler is supported only on arm64 and x86
which are all little endian.
Define GIT_BYTE_ORDER on msvc as little endian to avoid further checks.
