gdb: move all "current target" wrapper implementations to target.c

The following patch removes the current_top_target function, replacing
uses with `current_inferior ()->top_target ()`.  This is a problem for
uses in target.h, because they don't have access to the current_inferior
function and the inferior structure: target.h can't include inferior.h,
otherwise that would make a cyclic inclusion.

Avoid this by moving all implementations of the wrappers that call
target methods with the current target to target.c.  Many of them are
changed from a macro to a function, which is an improvement for
readability and debuggability, IMO.

target_shortname and target_longname were not function-like macros, so a
few adjustments are needed.
