David Marchand eeded2044a log: register with standardized names
Let's try to enforce the convention where most drivers use a pmd. logtype
with their class reflected in it, and libraries use a lib. logtype.

Introduce two new macros:
- RTE_LOG_REGISTER_DEFAULT can be used when a single logtype is
  used in a component. It is associated to the default name provided
  by the build system,
- RTE_LOG_REGISTER_SUFFIX can be used when multiple logtypes are used,
  and then the passed name is appended to the default name,

RTE_LOG_REGISTER is left untouched for existing external users
and for components that do not comply with the convention.

There is a new Meson variable log_prefix to adapt the default name
for baseband (pmd.bb.), bus (no pmd.) and mempool (no pmd.) classes.

Note: achieved with below commands + reverted change on net/bonding +
edits on crypto/virtio, compress/mlx5, regex/mlx5
