Support for WOLFPROV_LEAVE_SILENT return 0 suppression

[aidangarske]

Description

• Adds a WOLFPROV_LEAVE_SILENT macro and WOLFPROV_ENTER_NOEXIT macro pair that can be used with --debug and --leave-silent to suppress decode functions called by wp_*_decode() and functions that return 0 but are not actually failures like *_does_selection functions.
• This is not on by default because this could suppress real errors that return from decode functions. That said you can enable this but calling functions will need to be able to handle the failure case which in most cases would return correctly if called right. Either way in the output it will not show up.
• The WOLFPROV_ENTER_NOEXIT macro specifically adds a [NOEXIT] tag to the output of functions so users will know that there will be no leave function associated with the enter function.
• The goal with this was to reduce the clutter of "false" return 0's we get in various tests. When testing the ./scripts/cmd_test/do-cmd-test.sh` we got 1092 return 0's with unit test we get 206. After our changes we get 30 and 127 respectively the failures in unit test are ofc neg testing failures and the 30 in cmd test are expected behavior but shouldn't be suppressed.
