Add make.bat for exceptions sample

The cpp-baremetal-semihosting-exceptions sample is the only sample
missing a make.bat for running on Windows. A batch file has now been
added based on the others to carry out the same commands as the
Makefile, but without the grep commands since these are less likely
to be available.
