The error was that we were trying to link together
containers from boot package library (which depends template-haskell in boot package library)
template-haskell from in-tree package database
So the fix is to build containers in stage0 (and link against template-haskell built in stage0).
Fixes #21981

* refines the precedence levels, adding `qualPrec` and `funPrec` to better control parenthesization
* `pprParendType`, `pprFunArgType`, and `instance Ppr Type` all just call `pprType` with proper precedence
* `ParensT` constructor is now always printed parenthesized
* adds the precedence argument to `pprTyApp` as well, as it needs to keep track and pass it down
* using `>=` instead of former `>` to match the Core type printing logic
* some test outputs have changed, losing extraneous parentheses

Here we refactor the representation of info table provenance information
in object code to significantly reduce its size and link-time impact.
Specifically, we deduplicate strings and represent them as 32-bit
offsets into a common string table.
In addition, we rework the registration logic to eliminate allocation
from the registration path, which is run from a static initializer where
things like allocation are technically undefined behavior (although it
did previously seem to work). For similar reasons we eliminate lock
usage from registration path, instead relying on atomic CAS.
Closes #22077.
