* 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 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.

At the moment when I run make to build Prometheus npm tests are run as part of the process.
By default jest will run in interactive mode, unless CI env variable is set, meaning that it will run forever watching for file changes. This means that to build the binary I need to wait for jest to start and then press Q to exit it, which seems unnecessary.
Set CI=true for npm scripts so it always run in as a single run instead of watch mode.

* Makefile: compress web assets before build
This commit add compression before (and decompression after) prometheus
is build. This ensures that gzipped assets are embeded in the prometheus
binary, if the builtinassets build tag is passed. If the build tag is
not passed this step is still executed but has no effect.
All this is executed in a subshell so that we can run the decompress
step even if the build step fails, but retain the exit code of promu.
This cleanup could also cover interrupts, but I left that out for now.
