MSVC does not like bitfields with extra bits in them, so it made the GptEntry struct too big.
Fixed a missing return value in LoadFirmware().
Added some debug output.
Fixed calls to SetupTPM().
Tested with 'make && make runtests'. No errors.

It turned out that shared verified boot library fails to
work properly when compiled by msc in BIOS environment.
The culprit was identified as failing 64 bit logical
operations by preprocessor. It is probably possible to
come up with a certain compile flag set to fix the
operations, but it is not easy to modify and control the BIOS
compilation environment.
The alternative solution is to limit the size of the field
in question to 16 bits (especially since this is the only
part of the attributes field which is supposed to be
altered by firmware.
A union is being introduced in firmware/lib/cgptlib/include/gpt.h:GptEntry to allow
accessing the field both as a 64 bit entity and a top
16 bit field. All places where this field is used are
being modified appropriately.
tests/Makefile is being fixed to allow controlling test run
from the top level directory.
Tested by building everything and running tests.
All tests pass.
