Subject: [PATCH] Fix GCC -Werror=return-type

Summary:
X-link: https://github.com/facebook/yoga/pull/1910

GCC emits `-Wreturn-type` for `gridTrackSizeFromTypeAndValue` and
`styleSizeLengthFromTypeAndValue` because it does not suppress the
warning for exhaustive switches over C-style enums (unlike Clang).
Add `fatalWithMessage` after each switch to satisfy `-Werror=return-type`,
matching the existing pattern used in `Style.h` for similar exhaustive
switches.
