sim: Fix -Werror=shadow=local by changing mem to addr in sim_{read,write}

Browse Source 
m32c/cpu.h defines mem as enum value, which causes GCC 14 to emit

sim/m32c/gdb-if.c: In function ‘sim_read’:
sim/m32c/gdb-if.c:162:33: error: declaration of ‘mem’ shadows a previous local [-Werror=shadow=local]
  162 | sim_read (SIM_DESC sd, uint64_t mem, void *buf, uint64_t length)
      |                        ~~~~~~~~~^~~
In file included from ../../binutils-gdb/sim/m32c/gdb-if.c:38:
sim/m32c/cpu.h:83:3: note: shadowed declaration is here
   83 |   mem,
      |   ^~~

Fix this by renaming mem to addr in all sim_read and sim_write functions.
Most already used addr instead of mem. In one file, sim/rx/gdb-if.c, this
also meant renaming the local addr variable to vma.
