Fix: [Script] Improve ScriptText validation (#11721)

The validation is now done in two steps:
- First we get the list of parameters in the same order they used to be in encoded string
- Then we validate the parameter types like FormatString would use them while encoding the string

Codechange: automatic adding of _t to (u)int types, and WChar to char32_t

for i in `find src -type f|grep -v 3rdparty/fmt|grep -v 3rdparty/catch2|grep -v 3rdparty/opengl|grep -v stdafx.h`; do sed 's/uint16& /uint16 \&/g;s/int8\([ >*),;[]\)/int8_t\1/g;s/int16\([ >*),;[]\)/int16_t\1/g;s/int32\([ >*),;[]\)/int32_t\1/g;s/int64\([ >*),;[]\)/int64_t\1/g;s/ uint32(/ uint32_t(/g;s/_uint8_t/_uint8/;s/Uint8_t/Uint8/;s/ft_int64_t/ft_int64/g;s/uint64$/uint64_t/;s/WChar/char32_t/g;s/char32_t char32_t/char32_t WChar/' -i $i; done

Codechange: use std::string without const as return

Otherwise some compilers, e.g. MSVC, do not pick up that these are temporaries
and as such it will pass the temporaries to `const std::string &` instead of
the wanted `std::string &&`

Change: [Script] A ScriptText with too many parameters is now a fatal error

It should never happen as adding/setting parameters already checks that anyway.

Codechange: move casting a "const char *" to "char *" to the caller

It is not nice to have your definition say you won't change a value
while in fact the whole reason for your existance is to change it.

Codechange: rename str_validate to StrMakeValid(InPlace) (#9304)

This to be more explicit the function changes the value, and not
returns yes/no.
