Optimize GenerationAlloc() and SlabAlloc()
In a similar effort to 413c18401, separate out the hot and cold paths in
GenerationAlloc() and SlabAlloc() to avoid having to setup the stack frame
for the hot path.
This additionally adjusts how we use the GenerationContext's freeblock.

Support partition pruning on boolcol IS [NOT] UNKNOWN
While working on 4c2369ac5, I noticed we went out of our way not to
support clauses on boolean partitioned tables in the form of "IS
UNKNOWN" and "IS NOT UNKNOWN". It's almost as much code to disallow
this as it is to allow it, so let's allow
Add PostgreSQL::Test::Cluster::wait_for_event()
Per a demand from the author and the reviewer of this commit, this adds

introduced in 37b369dc67bc, while providing coverage for 7863ee4def65
that caused the startup process to throw "PANIC: could not locate a

injection_points: Add wait and wakeup of processes
This commit adds two features to the in-core module for injection
points:
- A new callback called "wait" that can be attached to an injection
point to make it wait.

Replace BackendIds with 0-based ProcNumbers
Now that BackendId was just another index into the proc array, it was
redundant with the 0-based proc numbers used in other places. Replace
all usage of backend IDs with proc numbers.
The only place where the term "backend id" remains is in a few
Redefine backend ID to be an index into the proc array
Previously, backend ID was an index into the ProcState array, in the
shared cache invalidation manager (sinvaladt.c). The entry in the
ProcState array was reserved at backend startup by scanning the array
for a free entry, and that was also
