tests: generic Makefile for user and baremetal test programs
This patch aims to provide a single unified Makefile for tests/test-progs.
This should make it easy to add either user or baremetal test programs
for any ISA.
Another major advantage is the ability to build every single test
program in one go, which makes it much more likely that we will notice
when they break on new compilers.
In this setup, a single source file can be used for both userland and
baremetal. Baremetal tests must be currently very basic however, since
there is no standard library support. However this already covers the
common use case of testing m5ops and ARM semihosting, e.g. m5_exit.c
runs on both userland and baremetal on ARM.
The initial test programs added are hello worlds to test the framework
itself, m5ops and arm semihosting SYS_EXIT.

+Build baremetal and userland C, C++ or assembly executables.

+
+Build all userland examples for the default ISA (x86):

+ make
+
+Only programs on the current directory and ISA named subdirectories e.g.
+x86, arm, arm64, riscv are build.
+
+The generated executables are placed under the directory out/
+
+Build all baremetal and userland examples for ARM:
+
+ make ISA=arm64 all
+
+Currently supported ISA values: x86, arm, arm64, riscv.
+
+Build only user or only baremetal:
+
+ make ISA=x86 user
+ make ISA=arm64 bare

+x86 currently only supports userland executables.
