Check each subsystem's memory under one DebugAllocator, not two

In a Debug build memory.zig put each subsystem allocator (core, frame, lsp,
tree-sitter, image, PDF) under a DebugAllocator of its own, which is what
reports that subsystem's leaks and makes memory.deinit panic on one. Beneath
it, past the fixed buffer, was the allocator the shell passed in: init.gpa,
which std.process.Init already makes a DebugAllocator in Debug. Every block
that spilled out of a fixed buffer was tracked, checked and given stack
traces twice, and in a test both layers sat on std.testing.allocator.

A Debug build now puts the page allocator beneath the subsystem
DebugAllocators, so each allocation passes through exactly one. The shells'
own gpa is still std.process.Init's DebugAllocator for everything else, and
a release build is unchanged: the subsystems sit on the gpa, no
DebugAllocator anywhere.
