feat: permit building a single hafnium platform
Introduced a PLATFORM makefile command line build option to permit
downstream solutions or integrations to build only the hafnium binary
that the solution is interested in. In particular this omits building
the test framework a downstream integration may not want to consume.
This also greatly improves the build time (and limits the external
dependencies) from the solution's perspective. Combined with the
existing PROJECT variable, the intent is to make the project build
just a bit more flexible.
Example usages:
make (builds all platforms from 'reference' project incl. tests)
make PLATFORM=secure_aem_v8a_fvp_vhe (builds only the SPMC targeting FVP
from the 'reference' project)
The following two examples are hypothetical if the external project
'foo' adheres to the working model proposed by project 'reference':
make PROJECT=foo (builds all targets from an externally provided project
'foo')
make PROJECT=foo PLATFORM=bar (builds only the 'bar' platform from
project 'foo')
