HelloWorld: Use ConsolePrint to simplify code and fix GCC build
AsciiSprint takes a CHAR8 buffer to write to whereas ConsoleWrite expects a UINT8 buffer. This causes GCC to complain: /.../sources/slimbootloader/PayloadPkg/HelloWorld/HelloWorld.c: In function ‘PayloadMain’: /.../sources/slimbootloader/PayloadPkg/HelloWorld/HelloWorld.c:36:25: error: pointer targets in passing argument 1 of ‘ConsoleWrite’ differ in signedness [-Werror=pointer-sign] 36 | ConsoleWrite (Message, Len); | ^~~~~~~ | | | CHAR8 * {aka char *} In file included from /.../sources/slimbootloader/PayloadPkg/HelloWorld/HelloWorld.h:18, from /.../sources/slimbootloader/PayloadPkg/HelloWorld/HelloWorld.c:8: /.../sources/slimbootloader/BootloaderCommonPkg/Include/Library/ConsoleOutLib.h:103:17: note: expected ‘UINT8 *’ {aka ‘unsigned char *’} but argument is of type ‘CHAR8 *’ {aka ‘char *’} 103 | IN UINT8 *Buffer, | ~~~~~~~~~~~^~~~~~ Let's avoid the whole problem and simplify the code too by just calling ConsolePrint instead.
