Fix crash backtraces on MS-Windows, broken by ASLR
* src/w32fns.c (DEFAULT_IMAGE_BASE): Define for 64-bit and 32-bit
MinGW builds.
(emacs_abort): Correct the callstack addresses for potential
relocation of the image base due to ASLR. This makes 'addr2line'
be able to interpret emacs_backtrace.txt when ASLR is in effect,
which it is on every modern version of MS-Windows. (Bug#63365)
* configure.ac (LD_SWITCH_SYSTEM_TEMACS) [mingw32]: Add comment
about keeping the image-base values in sync with w32fns.c.
* etc/DEBUG (How to disable ASLR): New section.
