macOS : cmake build is assuming SDKs are based on host OS version and hard-coded locations rather than available SDKs

# Repro

- watchman 2022.10.24.00 source
- macOS 13 (latest stable) Ventura arm64
- Xcode 14.0.1 (latest stable)
- brew (latest stable)

1. `brew install -s watchman`

2. Causes

`cmake -S . -B build -DENABLE_EDEN_SUPPORT=ON -DWATCHMAN_VERSION_OVERRIDE=2022.10.24.00 -DWATCHMAN_BUILDINFO_OVERRIDE=Homebrew -DWATCHMAN_STATE_DIR=/Users/ba/.homebrew/var/run/watchman -DCMAKE_INSTALL_PREFIX=/Users/ba/.homebrew/Cellar/watchman/2022.10.24.00 -DCMAKE_INSTALL_LIBDIR=lib -DCMAKE_BUILD_TYPE=Release -DCMAKE_FIND_FRAMEWORK=LAST -DCMAKE_VERBOSE_MAKEFILE=ON -Wno-dev -DBUILD_TESTING=OFF -DCMAKE_OSX_SYSROOT=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX12.sdk`

# Problem

1. Ventura ships with MacOSX12.sdk. SDKs vary widely and aren't tied to the host.

2. Xcode ships with CLT inside of itself (usually) at `{{xcode app of varying names and paths}}.app/Contents//Developer` The path is `$(mdfind 'kMDItemCFBundleIdentifier = "com.apple.dt.Xcode"')`

a. `/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX12.sdk` exists in Xcode 14.0.1 + macOS 13.
b. `/Library/Developer/CommandLineTools/SDKs/MacOSX13.sdk/usr/include` definitely doesn't exist in anything except (currently usable and unsupportable) beta software. It could be in the stand-alone CLT for Xcode 14, but that's pie in the sky.

# Remediation

Verify beforehand or let the tools figure out `-isysroot`.

## Build log snippet

Catch you later in the diffs and not too many SEVs :)
