  1. tpm2: allow tpm2_make_encryption_session() without bind key 

    Allow providing no bind key, and use ESYS_TR_NONE instead.

  2. tpm2: update tpm2 test for supported commands 

    The test expects TPM2_CC_FIRST - 1 and TPM2_CC_LAST + 1 to be unsupported, but
those are not necessarily invalid commands. Instead test known-invalid
commands. Also add some more valid commands.

  3. tpm2: use GREEDY_REALLOC_APPEND() in tpm2_get_capability_handles(), c… 

    …ap max value

Simplify the function with GREEDY_REALLOC_APPEND(). Also limit the size_t-sized
max value to UINT32_MAX since that's the maximum of the range this searches,
and the max parameter for tpm2_get_capability() is uint32_t.

  4. tpm2: change tpm2_unseal() to accept Tpm2Context instead of device st… 

    …ring

This matches the change to tpm2_seal(), which now accepts a Tpm2Context instead
of a device string.

This also allows using the same TPM context for sealing and unsealing, which
will be required by (future) test code when sealing/unsealing using a transient
key.

  5. tpm2: cache TPM's supported ECC curves 

    This brings the tpm2_supports_ecc_curve() api in line with the other
tpm2_supports_*() functions, of returning a boolean.
