- deptrac was rightly complaining that API (indirectly) depended on SDK through config/sdk. For now,
remove usage of Config\SDK\Configuration\Context
- update deptrac config to allow some new dependencies

psalm doesn't complain now, so that should be good

- make "register global" a function of Sdk, but keep the sdk builder's interface intact
- invent an API instrumentation context, similar to the one in config/sdk, to pass providers
  to instrumentations
- add an initial test of autoloading from a config file

in passing, remove some dead code for handling invalid booleans - config already handles this correctly

allow SDK created from config file to coexist with components using globals initializer

- drop storage from hook manager: can't guarantee that something else, eg swoole, won't modify storage
- drop context from hook manager: we must lazy-load globals via initializers, because not all instrumentations use SPI (although that may change in future)
- default hook manager to enabled

if no config provided, still try to load them. wrap registration in a try/catch/log

per review from Nevay, this will allow instrumentations to get things from Globals as late as possible
