On MacOs, starting with Big Sur 11.0.1, the system dynamic
libraries are no longer directly accessible on disk.
They are still available through dlopen and friends. For getting
access to the images (and their debug symbol), Apple provides,
in the developper kit, the tools to extract the files. Note that
this is handled as a database of all system libraries, where ASLR
is in place such that segments of a given library are no longer
contiguous in memory (dbghelp doesn't currently handle this).
Apart from not having image information nor debug information,
another side effect is that dbghelp tries every time it refreshes the
mach-o module list to reload any library for which it didn't have
an image file. This can be lengthy (esp when a typical process has
more than 300 modules loaded).
This patch forces the creation of the dbghelp module even if the
image file isn't found.
This patch cuts startup time of 'winedbg notepad' from 9.9 to 7.4s.
YMMV.

Currently, dbghelp returns the source file either:
- in DOS format when native module option isn't enabled
- as stored in debug info format otherwise
This used to work for PE modules inside ELF shared libraries but is broken
since evolution to REAL modules. This generates several issues:
- winedbg does not always set the native module option when calling dbghelp
for source file related functions, leading to heterogenous output to user
- some dbghelp function rely on matching source paths, hence leading to
errors in winedbg when mixing the two formats for the same source file.
Introduce a new Wine only dbghelp option to return the source paths as they
are stored inside debug information format, and activate it unconditionaly
inside winedbg.
This fixes some failure cases of command 'break <NN>' in winedbg.

Expose the real path of a loaded module (potentially read from
WINEDLLDIR or WINEBUILDDIR or overriden load order or ...). This
improves gdb integration by passing the real path to the loaded
modules (instead of the paths in c:\windows\ system subdirectories).
Introduce new Wine only dbghelp's extended option to enable the
feature.

Add support of flag MinidumpWithFullMemory in function
MinidumpWriteDump. A Memory64ListStream is added to the minidump
streams and all memory regions of the process with MEM_COMMIT state
are written to the last part of the minidump file.

Also add a number of missing prototypes, especially 64bit or Unicode
versions of existing prototypes, and the related structures. Update
win32.api to fix the winapi_check warnings.
