Ensure Todos counters doesn't count Todos for projects pending delete

Disable the unlink feature for SAML connected accounts (social login).

This disables the ability to manually unlink your SAML account, if you have one connected. In certain scenarios, the only allowed login mechanism can be SAML, and if you unlink your account you will be locked out of the system (configuration dependent).

Track method call times/counts as a single metric

This changes method call tracking so only a single metric is emitted regardless of the number of calls. This allows us to more accurately measure the total execution time of a method as well as the number of times a method is called. See 851e3ff7578973c2206628424eac3b951a3c656d for more details.

Method call tracking tracked calls individually meaning the end statistics may not always be accurate enough to get a good understanding of where time is spent.

Also document the clipboard_button_with_class method.

Fixes #18794.

Previously we'd create a separate Metric instance for every method call
that would exceed the method call threshold. This is problematic because
it doesn't provide us with information to accurately get the _total_
execution time of a particular method. For example, if the method
"Foo#bar" was called 4 times with a runtime of ~10 milliseconds we'd end
up with 4 different Metric instances. If we were to then get the
average/95th percentile/etc of the timings this would be roughly 10
milliseconds. However, the _actual_ total time spent in this method
would be around 40 milliseconds.

To solve this problem we now create a single Metric instance per method.
This Metric instance contains the _total_ real/CPU time and the call
count for every instrumented method.
