Settings0 used to be a Map[Scope, AttributeMap], and is now a
Map[ScopedKey[x], x].
This is better because we don't need to decompose all ScopedKey[x]
into a Scope and an AttributeKey[x], for recomposing it back later,
which duplicates all ScopedKey[x]. It reduces the number of long-living
ScopedKey[x] by 8%, and the total number of instances by 1.4%.
Also it improves the performance of Settings0, which was responsible of
2.95% of the total CPU time, and is now responsible of 0.41%.
**Problem**
Current implementation of testQuick depends on the concept of timestamp,
which probably won't work well with the new consistent analysis store or
the idea of remote caching.
**Solution**
This is a step towards cached testing by making the incrementality hermetic
(no longer depends on the timestamp). Instead this calculates the aggregated
SHA-256 of the class files involved in the test.

This adds a new setting `enableConsistentCompileAnalysis`,
which enables the new "Consistent" Analysis format,
which is faster and more repeatable than the status quo.
This is initialized to `true` by default.
It can be opted out either by the setting or using
`-Dsbt.analysis2024=false`.
**Problem**
Plugins are topologically sorted, but plugins with equal weigh could
modify the same key via `~=` etc, resulting in different builds
depending on the artifact.
**Solution**
This attempts to fix that by first sorting the selected plugins
by the class name before sorting it topologically.

Problem
-------
sbtn 1.8.1 was built using ubuntu-latest, which meant picking up newer
glibc.
Solution
--------
This downgraded the ubuntu machine to build sbtn.
Migrates TreeView.scala to use Contraband from scala.util.parsing.json,
because this is now deprecated.
The TreeView logic is used in the dependencyBrowseTree task.
Since build.sbt is compiled/evaluated in `sbt.compiler.Eval`,
this commit introduces a `BuildServerEvalReporter` to redirect
the compiler errors to the BSP clients.
A new `finalReport` method is added in the new `EvalReporter` base class
to reset the old diagnostics.
* Refactor so as to be testable
* Queue stores the _beginning_ timestamp of each GC time delta
* Message states the correct time over which the GC time was recorded
* Add heap stats from java.lang.Runtime to the message
This test works fine locally on all platforms but there are issues in
CI. I think that it might work ok with 1.4.2 without a lot of extra
effort so I'm going to disable it for now.
