* Add $YARP_SERIALIZE_ONLY_SEMANTICS_FIELDS to control where to serialize location fields at templating time,
this way there is no overhead for either case and nothing to check at runtime.
* Add a byte in the header to indicate whether location fields are included as expected.
* Fixes https://github.com/ruby/yarp/issues/807
* Simplify the build-java CI job now that the FFI backend is available so JRuby can serialize.
* Support keeping some location fields which are still needed until there is a replacement

CI is currently failing due to an issue with Ripper on the latest
TruffleRuby version. This commit removes the offending tests from
running, to ensure CI is green again.

Introduces a new flavor of unescaping, YP_UNESCAPE_WHITESPACE, which
is the same as MINIMAL but also unescapes whitespace.
Note that a spanning_heredoc.txt fixture test is updated to be less
wrong, but YARP's behavior doesn't yet fully match Ruby in this case.
Fixes https://github.com/ruby/yarp/pull/1505https://github.com/ruby/yarp/commit/0af69bdeb1

Although the specification for UUIDv7 is still in draft, the UUIDv7
algorithm has been relatively stable as it progresses to completion.
Version 7 UUIDs can be very useful, because they are lexographically
sortable, which can improve e.g: database index locality. See section
6.10 of the draft specification for further explanation:
https://datatracker.ietf.org/doc/draft-ietf-uuidrev-rfc4122bis/
The specification allows up to 12 bits of extra timestamp precision, to
make UUID generation closer to monotonically increasing. This provides
between 1ms and ~240ns of timestamp precision. At the cost of some code
complexity and a small performance penalty, a kwarg may specify any
arbitrary precision between 0 and 12 extra bits. Any stronger
guarantees of monotonicity have considerably larger tradeoffs, so
nothing more is implemented. This limitation is documented.

Previously, we were hardcoding the expected evaluation value. Now,
instead, we structure it so that we compare the YARP evaluation value
against CRuby's evaluation value.
By compacting into slots with pinned objects first, we improve the
efficiency of compaction. As it is less likely that there will exist
pages containing only pinned objects after compaction. This will
increase the number of free pages left after compaction and enable us to
free them.
This used to be the default compaction method before it was removed
(inadvertently?) during the introduction of auto_compaction.
This commit will sort the pages by the pinned slot count at the start of
a major GC that has been triggered by explicitly calling GC.compact (and
thus setting objspace->flags.during_compaction).
It works using the same method by which we sort the heap by empty slot
count during GC.verify_compaction_references.
Previously it was only being sorted during the verify compaction
references stage - so would only happen during testing.
This commit allows us to sort the heap prior to each explicit GC.compact
