Ignore more temporary files by default

files.exclude allows users to define which things should be not in file explorer, should not be searched and not indexed. They can still be opened using "file open".

Reasonably the default https://github.com/microsoft/vscode/blob/4c31caa886a6f66fa3cff5f2654e4fa7fdad8f9c/src/vs/workbench/contrib/files/browser/files.contribution.ts#L155-L159 includes commonly used VCS' subfolders like .git, .svn, ...

The last commit there 1d9dc8b261cac5a65bea4e8ce97229511c78231b "web - filter out *.crswap via files.exclude" sneaked in the windows-only Thumbs.db (which I find a reasonable addition in any case), the previous fa0bc23382316d6ec2cd6bd7d9b198f0511e3b42 added CVS, with previous .hg and .svn additions.

I suggest to add more files there and while I initially had a bunch of files in my mind, including the list from the end, I've stepped down and suggest to at least add files ending with a~ because those are, over several systems and software, always temporary files #228981.

I'd like the community to:

vote for general addition of more entries, staring with `/~`
discuss which entries should be added, possibly including (this list is from a portable C build)

*.la
*.lo
*.o
*.so
*.obj
*.dll
*.lib
*.exe

*cache*
*-coverage
*.bak
*.gcda
*.gcno
*.diff
*.patch
*.tmp
cscope.*
TAGS

ipch
.vs
*.aps
*.ncb
*.*sdf
*.suo

.libs
.deps

Users can override that (which then means to also include the default values wanted) in their settings (so workspace/user/machine scope), so files that are "only very seldom should be used in the UI" can still be included (for example if someone wants his Thumbs.db or TAGS files shown), but we should still consider the likelyness (.deps seems to also be "something .NET/C#, not sure if this is like .vscode which you want to have included by default, for example).

Entries like *cache* are likely bad, thinking of for example package names including it. But who should have .bak or .tmp files shown and searched...
