When executing internal queries, it is important that the developer
will decide if to cache the query internally or not since internal
queries are cached indefinitely. Also important is that the programmer
will be aware if caching is going to happen or not.
The code contained two "groups" of `query_processor::execute_internal`,
one group has caching by default and the other doesn't.
Here we add overloads to eliminate default values for caching behaviour,
forcing an explicit parameter for the caching values.
All the call sites were changed to reflect the original caching default
that was there.

Instead of lengthy blurbs, switch to single-line, machine-readable
standardized (https://spdx.dev) license identifiers. The Linux kernel
switched long ago, so there is strong precedent.
Three cases are handled: AGPL-only, Apache-only, and dual licensed.
For the latter case, I chose (AGPL-3.0-or-later and Apache-2.0),
reasoning that our changes are extensive enough to apply our license.
The changes we applied mechanically with a script, except to
licenses/README.md.
Closes#9937
And rename to get_batchlog_mutation_for while at it,
as it's about the batchlog, not batch_log.
This resolves a circular dependency between the
batchlog_manager and the storage_proxy that required
it in the case.

storage_proxy.hh is huge and includes many headers itself, so
remove its inclusions from headers and re-add smaller headers
where needed (and storage_proxy.hh itself in source files that
need it).
Ref #1.
Corresponding overload of `storage_proxy::mutate_locally`
was hardcoded to pass `db::commitlog::force_sync::no` to the
`database::apply`. Unhardcode it and substitute `force_sync::no`
to all existing call sites (as it were before).
`force_sync::yes` will be used later for paxos learn writes
when trying to apply mutations upgraded from an obsolete
schema version (similar to the current case when applying
locally a `frozen_mutation` stored in accepted proposal).

In order to add tracing to places where it can be useful,
e.g. materialized view updates and hinted handoff, tracing state
is propagated to all applicable call sites.
1. Move tests to test (using singular seems to be a convention
in the rest of the code base)
2. Move boost tests to test/boost, other
(non-boost) unit tests to test/unit, tests which are
expected to be run manually to test/manual.
Update configure.py and test.py with new paths to tests.
