Summary:
These are often not expected to be used directly e.g.
```
TEST_F(Fixture, X) {
^ // "Fixture_X_Test" expanded in the macro should be down ranked.
}
```
Only doing this for sema for now, as such symbols are mostly coming from sema
e.g. gtest macros expanded in the main file. We could also add a similar field
for the index symbol.

This should make all-scope completion more usable. Scope proximity for
indexes will be added in followup patch.

Summary:
The following are metrics for explicit member access completions. There is no
noticeable impact on other completion types.
Before:
EXPLICIT_MEMBER_ACCESS
Total measurements: 24382
All measurements: MRR: 62.27 Top10: 80.21% Top-100: 94.48%
Full identifiers: MRR: 98.81 Top10: 99.89% Top-100: 99.95%
0-5 filter len:
MRR: 13.25 46.31 62.47 67.77 70.40 81.91
Top-10: 29% 74% 84% 91% 91% 97%
Top-100: 67% 99% 99% 99% 99% 100%
After:
EXPLICIT_MEMBER_ACCESS
Total measurements: 24382
All measurements: MRR: 63.18 Top10: 80.58% Top-100: 95.07%
Full identifiers: MRR: 98.79 Top10: 99.89% Top-100: 99.95%
0-5 filter len:
MRR: 13.84 48.39 63.55 68.83 71.28 82.64
Top-10: 30% 75% 84% 91% 91% 97%
Top-100: 70% 99% 99% 99% 99% 100%
* Top-N: wanted result is found in the first N completion results.
* MRR: Mean reciprocal rank.
Remark: the change seems to have minor positive impact. Although the improvement
is relatively small, down-ranking non-instance members in instance member access
should reduce noise in the completion results.

Summary:
We now compute a distance from the main file to the symbol header, which
is a weighted count of:
- some number of #include traversals from source file --> included file
- some number of FS traversals from file --> parent directory
- some number of FS traversals from parent directory --> child file/dir
This calculation is performed in the appropriate URI scheme.
This means we'll get some proximity boost from header files in main-file
contexts, even when these are in different directory trees.
This extended file proximity model is not yet incorporated in the index
interface/implementation.

Summary:
Now we have most of Sema's code completion signals incorporated in Quality,
which will allow us to give consistent ranking to sema/index results.
Therefore we can/should stop using Sema priority as an explicit signal.
This fixes some issues like namespaces always having a terrible score.
The most important missing signals are:
- Really dumb/rarely useful completions like:
SomeStruct().^SomeStruct
SomeStruct().^operator=
SomeStruct().~SomeStruct()
We already filter out destructors, this patch adds injected names and
operators to that list.
- type matching the expression context.
Ilya has a plan to add this in a way that's compatible with indexes
(design doc should be shared real soon now!)

Summary:
This signal is considered a relevance rather than a quality signal because it's
dependent on the query (the fact that it's completion, and implicitly the query
context).
This is part of the effort to reduce reliance on Sema priority, so we can have
consistent ranking between Index and Sema results.

Summary:
Code completion scoring was embedded in CodeComplete.cpp, which is bad:
- awkward to test. The mechanisms (extracting info from index/sema) can be
unit-tested well, the policy (scoring) should be quantitatively measured.
Neither was easily possible, and debugging was hard.
The intermediate signal struct makes this easier.
- hard to reuse. This is a bug in workspaceSymbols: it just presents the
results in the index order, which is not sorted in practice, it needs to rank
them!
Also, index implementations care about scoring (both query-dependent and
independent) in order to truncate result lists appropriately.
The main yak shaved here is the build() function that had 3 variants across
unit tests is unified in TestTU.h (rather than adding a 4th variant).
