Getters should nearly always be const when they return a
non-const pointer to an unowned object. Saves a bit of
code along the way.
Grep for similar occurrences and add "const".

Define constant values in the public API for the valid values of alert
button type, alert icon type, and beep type. Replace various magic
numbers through out the code base using these values. Also replace the
XFA specific versions with an enum class that is guaranteed to have the
same values, instead of #defines that just happen to.
This CL does not attempt to add error checking on these values, since
it currently doesn't exist so adding it may cause regressions.

In this function a string is converted to UTF8, if there are
non-printing characters in the original string, the generated string
will be shorter. Thus using the original string length for iteration
range will cause an OOB read.

Many of these are converting ByteString => c_str => ByteStringView, since
the ByteStringView ctor is implicit. This is unfortunate, since that
involves a strlen() which the ByteString already knows if we use
AsStringView() instead.
This changed one test result where we can now return the string
"\0" instead of "" -- since strlen no longer eats the NUL. This
seems consistent, say, with String.fromCharCode().

We used to assume that a global proxy object could be distinguished
by it not having two internal fields, but that invariant isn't
correct. Instead, flag it as such so the block of code at line 126
will check the prototype to find an actual object.
Squeeze some bytes out of the tags while were at it, no reason for
them to be wide. Also remove GetGlobalObjectFromContext() helper, for
transparency into what's really going on in v8. This then shows a
needless retrieval of an object we already have in one case.
