`PhysicalConstants.jl` fails to precompile on master.

[N5N3]

On master using PhysicalConstants seems run into a dead loop. (CPU usage is not 0)
On 1.7 everything seems OK.

[giordano]

For the record, this is getting stuck at https://github.com/JuliaPhysics/PhysicalConstants.jl/blob/221b3bee8dd001294ad7f3897bfb2f9e64809b4e/src/PhysicalConstants.jl#L87 for derived physical constants, for example https://github.com/JuliaPhysics/PhysicalConstants.jl/blob/221b3bee8dd001294ad7f3897bfb2f9e64809b4e/src/codata2014.jl#L39. If I comment out all those assertions, I can precompile the package, but doing measurement(CODATA2014.PlanckConstantOver2pi) still results in a dead lock:

julia> using PhysicalConstants.CODATA2014, Measurements

julia> measurement(CODATA2014.PlanckConstantOver2pi)

Given the files referenced in the stacktrace I presume we should ping @aviatesk? Note that the Measurements.measurement method which goes wild is defined at https://github.com/JuliaPhysics/PhysicalConstants.jl/blob/221b3bee8dd001294ad7f3897bfb2f9e64809b4e/src/PhysicalConstants.jl#L68-L69.

This might be akin to #43542, though the cause and solution are likely quite different

commit 63f62943e13d47c917e4136bc13c062a2b09fbe1
Author: Jameson Nash <vtjnash@gmail.com>
Date:   Fri Dec 17 16:59:21 2021 -0500

    Allow const declarations on mutable fields (#43305)

    Mark some builtin types also, although Serialization relies upon being
    able to mutilate the Method objects, so we do not yet mark those.

    Replaces #11430

Before that commit, it takes about 30s to precompile PhysicalConstants.jl on my pc. (For comparing, the time cost is 24s on 1.7.1)

It took me 17 seconds to precompile PhysicalConstants.jl and all of its dependencies

[N5N3]

Well, I just run @time using PhysicalConstants on a fresh-built julia.
So I guess 24s includes time for dependencies

I just opened a PR to Measurements.jl and found that CI is hanging on Julia nightly: https://github.com/JuliaPhysics/Measurements.jl/runs/4649844099?check_suite_focus=true. I just recompiled latest master of Julia and found that simple things like
