Revert "[lldb] [mostly NFC] Large WP foundation: WatchpointResources (#68845)"

...and follow ups.

As it has caused test failures on Linux Arm and AArch64:
https://lab.llvm.org/buildbot/#/builders/96/builds/49126
https://lab.llvm.org/buildbot/#/builders/17/builds/45824

```
  lldb-shell :: Subprocess/clone-follow-child-wp.test
  lldb-shell :: Subprocess/fork-follow-child-wp.test
  lldb-shell :: Subprocess/vfork-follow-child-wp.test
```

This reverts commit a6c62bf1a4,
commit a0a1ff3ab4 and commit
fc6b72523f.
