Improve handling of verbosity in bindings

The macro AFB_BINDING_PRAGMA_NO_VERBOSE_MACRO is removed.

The macro AFB_BINDING_PRAGMA_NO_VERBOSE_UNPREFIX is removed.

The macro AFB_BINDING_PRAGMA_KEEP_VERBOSE_UNPREFIX is now used to
activate the weakly named verbose macros DEBUG, INFO, NOTICE,
WARNING, ERROR.

The macros AFB_BINDING_PRAGMA_NO_VERBOSE_DATA and
AFB_BINDING_PRAGMA_NO_VERBOSE_DETAILS can be used to tune what
verbose parts are to be emitted:

If AFB_BINDING_PRAGMA_NO_VERBOSE_DATA is defined then the macro
will only report the file and the line that emitted the message.
This mode is intended to reduce the count of static data plugin
the binary.

If AFB_BINDING_PRAGMA_NO_VERBOSE_DATA is not defined and
AFB_BINDING_PRAGMA_NO_VERBOSE_DETAILS is defined, this is the opposite:
the messages are emitted but not the file, line and function.

When none of these 2 are difened, everything is emitted: the message
and the details.
