Add a setting for disable_exec_load

[segiddins]

See #4852

Hmmm I was actually thinking of a flag on exec, like exec --no-load. This is good too, though. Document this setting in man/bundle_config and I think this is good!

I personally prefer settings to flags for things that are rarely needed

I was thinking of the flag for the use case where one particular command only works with load disabled, but you don't want to lose the performance improvements generally. But shipping a setting seems fine for now, you can do a one-off using env.
