tex-memoir{,-doc}: update to 3.7q

-- Added memhfixc autoloading to memoir (via \AtEndPackage{hyperref}...), then
   the equivalent code can be removed from hyperref
-- now auto loads the etoolbox package in order to enable a future patching
   approach instead of overwriting kernel macros
-- changed definition of \medspace into \providecommand for better testing
   with older kernels
-- added some code to a hook provided by footmisc fixing a bug with the
   combination of memoir+footmisc+reledmac, especially the 2022 update of
   footmisc
-- fixed typo in manual regarding \setupmaintoc
-- The LaTeX team changed the order of the file/package hook names into a more
   precise scheme. \AtBegin/EndFile, \AtBegin/EndPackage, \AtBegin/EndClass
   changed accordingly
