LibJS: Remove ECMAScriptFlags value from JS_ENUMERATE_REGEXP_FLAGS

Browse source 
All regex flags supported by LibJS currently correspond to a LibRegex
option, but this is not the case for the RegExp.prototype.hasIndices
proposal, which is handled entirely in RegExpBuiltinExec. Remove the
flag mapping to prepare for this. This incurs a bit of an optimization
loss in the flag getters, as we now do a substring search, but we can
revisit the getter implementation if it becomes an issue.
