1df35f6c77 tpm2: Change marshalled fields of OBJECT (StateFormatLevel 6)
Bump up the StateFormatLevel to 6 and use it to introduce a new OBJECT
marshalling format version '4' that slighly changes how an OBJECT is
marshalled:

- only marshal the private exponent for an RSA key
- always marshal the new hierarchy field

The marshalling code can still write previous version '3' when an older
StateFormatLevel is used to support backwards compatibility.

Adjust the test cases marshalling an RSA key OBJECT to check against
expected sizes across a series of StateFormatLevels.

bb4dafb1e7 tpm2: NVMarshal: Introduce MAX_MARSHALLED_OBJECT_SIZE
Introduce the #define MAX_MARSHALLED_OBJECT_SIZE to be used for a size of
a byte buffer that is supposed to hold a marshalled OBJECT. The number
is not exact but provides for a 'safe' size of a buffer.

Add a test case to check that MAX_MARSHALLED_OBJECT_SIZE is sufficient.
The test case needs access to ANY_OBJECT_Marshal, which is only available
when -static can be used for linking since otherwise the function is
private to the library. Static linking the test case does not work when
test-coverage is enabled, therefore disable statically linked test cases
in when test-coverage is enabled and give control to the user to disable
statically linked test cases in other cases as well.
