package/wolftpm: Add config options for TPM 2.0 extra capabilities

Browse Source 
Some TPM 2.0 chips offer extra capabilities. This patch adds additional
configuration options to the wolftpm package, so such capabilities can
be available to the user. For example, the STMicroelectronics ST33 and
Nuvoton NPCT750 both offer secure GPIO. Due to chip differences, wolfTPM
requires explicit configuration options to enable the extra capabilities.
