These changes are required to allow a new type-safe approach to TBD
nodes, that will come in a separate commit.
This introduces:
* the possibility to add properties to the root `Element`
* a functor taking tags to the corresponding binding trap entry
* `hasProp()` methods for optional properties in QL
* `getPrimaryQlClass()` method
Properties marked with `predicate` in the schema are now accepted.
* in the dbscheme, they will translate to a table with a single `id`
column (and the table name will not be pluralized)
* in C++ classes, they will translate to `bool` fields
* in QL classes, they will translate to predicates

Providing `--dynamic_mode=fully` (for example setting it in
`local.bazelrc`) will now work.
All runfiles are now copied in the extractor pack: in dynamic mode,
those will be the executable and the dynamic libraries, while in static
mode only the executable will be part of the runfiles.
Setting the correct `LD_LIBRARY_PATH` in `qltest.sh` then allows to
run tests with this pakcage. If we need something more, we can switch to
a wrapper script in place of `extractor` in the future.
Notice that `LD_LIBRARY_PATH` is also set in static mode, but that has
no consequence.
This checks in the trapgen script generating trap entries in C++.
The codegen suite has been slightly reorganized, moving the templates
directory up one level and chopping everything into smaller bazel
packages. Running tests is now done via
```
bazel run //swift/codegen/test
```
With respect to the PoC, the nested `codeql::trap` namespace has been
dropped in favour of a `Trap` prefix (or suffix in case of entries)
within the `codeql` namespace. Also, generated C++ code is not checked
in in git any more, and generated during build. Finally, labels get
printed in hex in the trap file.
`TrapLabel` is for the moment only default-constructible, so only one
single label is possible. `TrapArena`, that is responsible for creating
disjoint labels will come in a later commit.
