[lldb][NFC] Fix all formatting errors in .cpp file headers

Summary:
A *.cpp file header in LLDB (and in LLDB) should like this:
```
//===-- TestUtilities.cpp -------------------------------------------------===//
```
However in LLDB most of our source files have arbitrary changes to this format and
these changes are spreading through LLDB as folks usually just use the existing
source files as templates for their new files (most notably the unnecessary
editor language indicator `-*- C++ -*-` is spreading and in every review
someone is pointing out that this is wrong, resulting in people pointing out that this
is done in the same way in other files).

This patch removes most of these inconsistencies including the editor language indicators,
all the different missing/additional '-' characters, files that center the file name, missing
trailing `===//` (mostly caused by clang-format breaking the line).

ProcessInstanceInfoMatch: Don't match processes with no name if a name match was requested, take 2

Summary:
The previous attempt at making nameless process not match when searching for a
given name failed because the macos implementation was depending on this detail
in its partial matching strategy. Doing partial matching to avoid expensive
lookups is a perfectly valid thing to do, the way it was implemented seems
somewhat unexpected.

This patch implements it differently by providing special
methods in the ProcessInstanceInfoMatch which match only a subset of fields,
and changes mac host code to use those instead.

Then, it re-applies r373925 to get make the ProcessInstanceInfoMatch with a
name *not* match a nameless process.

ProcessInstanceInfoMatch: Don't match processes with no name if a name match was requested

Since D68289, a couple of tests on linux started being extremely flaky.
All of them were doing name-based attaching and were failing because
they couldn't find an unambiguous process to attach to.

The patch above changed the process finding logic, so that failure to
find a process name does not constitute an error. This meant that a lot
more transient processes showed up in the process list during the test
suite run. Previously, these processes would not appear as they would be
gone by the time we went to read their executable name, arguments, etc.

Now, this alone should not cause an issue were it not for the fact that
we were considering a process with no name as if it matched by default
(even if we were explicitly searching for a process with a specified
name). This meant that any of the "transient" processes with no name
would make the name match ambiguous. That clearly seems like a bug to me
so I fix that.

[process list] make the TRIPLE column wider

Summary:
Now that `process list` works better on the android platform, the arch aarch64-unknown-linux-android appears quite often.
The existing printed width of the TRIPLE column is not long enough, which doesn't look okay.
E.g.
```
1561 1016 aarch64-unknown-linux-android ip6tables-restore
1999 1 aarch64-unknown-linux-android tlc_server
2332 982 com.android.systemui
2378 983 webview_zygote
```

Now, after adding 6 spaces, it looks better

```
PID PARENT USER TRIPLE NAME
====== ====== ========== ============================== ============================
...
1561 1016 aarch64-unknown-linux-android ip6tables-restore
1999 1 aarch64-unknown-linux-android tlc_server
