feat(ivy): accept multiple values for exportAs in the compiler (#28001)

Browse Source 
exportAs in @Directive metadata supports multiple values, separated by
commas. Previously it was treated as a single value string.

This commit modifies the compiler to understand that exportAs is a
string[]. It stops short of carrying the multiple values through to the
runtime. Instead, it only emits the first one. A future commit will modify
the runtime to accept all the values.
