690cb6fa48 Config: Fixes JSON parsing of "ArgumentHandler" types 
When 4d109c9ce0 fixed parsing strenum
types in the json, it also added `ArgumentHandler` types to the json
parsing. This was incorrect as those types are already stored in the
json in their decoded numerical format.

Without this change, all config options with `ArgumentHandler` will
decode as "0" which is incorrect. The main killer here is that SMCChecks
gets disabled (visible in both FEXConfig and when applications are
running) which was causing spurious failures.

8e1aaa0559 Library Forwarding: Avoid de-sugaring pointee types 
Doing so would accidentally resolve typedefs before. This code isn't needed
now that integers are mapped to fixed-size equivalents anyway.

6d58ea31b9 Add cmake option DISABLE_CLANG_PRESERVE_ALL 
Forces disabling use of __attribute__((preserve_all)).
Until CI uses clang17, where this attribute was added, instcountci fails
when FEX is compiled with clang>=17.
