[TIMOB-28510] iOS: API detection causes strings starting with Ti or Titanium to be inserted as Ti Symbol Macros

Description

_There are probably other cases that cause this, like comments_ If a string starts with Ti or Titanium then it will be detected as Titanium API usage and be inserted into the TI_SYMBOL_MACROS definition. This will then cause a compile error like below if the string is not compatible"

[TRACE] error: conditional compilation flags must be valid Swift identifiers (rather than 'ISSUE?')
[TRACE] error: conditional compilation flags must be valid Swift identifiers (rather than 'ISSUE?TOUPPERCASE')

I think this fix will have two parts: * Firstly, improve the detection of API usage in the babel plugin we use * Secondly, when mapping the symbols, reject any that do not match the format we expect

const win = Ti.UI.createWindow();
win.add(Ti.UI.createLabel({
    text: 'Ti In A String Causes Issues?'.toUpperCase()
}));
win.open();

Steps to reproduce

1. Add the above code to an existing app 2. Build for -p ios -T dist-appstore

Actual

Compile error

Expected

No compile error
