Rename INVALID_FUNCTION_NAME to FUNCTION_ADDRESS_NOT_AVAILABLE.

aarongreig · aarongreig · commit 18d229b5c4c1 · 2023-12-28T15:27:31.000Z
This lines up better with the original PI error code and what it was
meant to convey.

Also clarify the spec around return codes for
urProgramGetFunctionPointer and update the relevant CTS test.
