* tsdb: avoid slice-to-interface allocation in EnsureOrder
This is pulling the `seriesRefSlice` out of the loop, so the compiler
doesn't allocate a new one on the heap every time.

* tsdb: use pointer type in Pool for EnsureOrder
As noted by staticcheck, Pool prefers the objects in the pool to have
pointer type. This is a little more fiddly to code, but avoids
allocation of a wrapper object every time a slice is put into the pool.
Removed a comment that said fixing this has a performance penalty: not
borne out by benchmarks.

This commit adds an alert in the prometheus mixin which triggers when
Prometheus has failed scrapes that have exceeded the configured
sample_limit for that job.

This commit ensures 64-bit integers are used in various tests that other wise
fail in 32-bit architectures.
It also adds support for int64 and uint64 types in the template.convertToFloat
function to support the test changes.

Per Julien's feedback on #10369, we're choosing to be consistent with
data types inside the stats structure (ints) rather than with the points
format that is part of the normal query responses (strings). We have
this option because this data cannot be NaN/Inf.

This exactly corresponds to the statistic compared against MaxSamples
during the course of query execution, so users can see how close their
queries are to a limit.

This allows other implementations to inject their own statistics that
they're gathering in data linked from the context.Context. For example,
Cortex can inject its stats.Stats value under the `cortex` key.

We always track total samples queried and add those to the standard set
of stats queries can report.
We also allow optionally tracking per-step samples queried. This must be
enabled both at the engine and query level to be tracked and rendered.
The engine flag is exposed via a Prometheus feature flag, while the
query flag is set when stats=all.

This change makes sure that the git worktree is not changed while
compressing assets, making it better for local development.
To achieve this, the compression script keeps the un-compressed assets
and generates the go:embed directory when compressing the files.
A .gitignore file has been added to ignore generated files.

This will avoid codemirror-promql clients to choose manually between cjs or esm so the bundler can decide.

* Compare equality of label.Label structs directly
Compare the structs using `==` instead of the name and value
of each label. This is functionally equivalent and about ~10%
faster in my testing.
