BaseTools: Warn the improper usage of Depex for module types

According to INF specification, if the module is not a library (no
LIBRARY_CLASS in the [Defines] section) and the MODULE_TYPE is SEC,
SMM_CORE, DXE_CORE, PEI_CORE, UEFI_DRIVER, UEFI_APPLICATION or
HOST_APPLICATION a Depex section is not permitted. Thus, this patch
adds a check when retrieving dependency expression. If the module
has [Depex] section but it's not permitted by INF specification,
just throw warning message to warn.
