Remove unused or unnecessary compiler specific marcos in FML. (#17101)
Remove unused or unnecessary compiler specific marcos in FML. (#17101)

Macros to control inlining are not used and we explicitly recommending against
playing with compiler inlining. The macros for alignment became part of the
standard in C++11 and we already use the standard variants over these macros
(see `PointerData`). The formatters are unused as well and we use the stream
based variants for formatting.
