Go custom labels from pprof labels
1caabb1 
Add support for a collection of 10 labels that can be attached to
every sample.  Process the go pprof labels into these labels.

Test that this works for Go 1.23 and Go 1.24 with new kernel tests.

Native custom labels

If a process links against the custom labels library:

https://github.com/polarsignals/custom-labels

Or is statically linked and has the custom_labels_abi_version exported
symbol then we will try to read custom labels out of the TLS name
'custom_labels_current_set'.
