Bug 208789 - patch 1 - Create an intl::GeneralCategory enum for UnicodeProperties::CharType() to return, to avoid directly referring to ICU4C constants or mapping via harfbuzz constants. r=platform-i18n-reviewers,nordzilla

No change in behavior; this just gives us our own version of the general category constants,
so we can avoid depending on ICU's constants elsewhere in the codebase.

Bug 1818305 - Part 2: Add a streamStatus method to nsIInputStream, r=xpcom-reviewers,necko-reviewers,geckoview-reviewers,valentin,jesup,m_kato,mccr8

This is semantically similar to the existing available() method, however will
not block, and doesn't need to do the work to actually determine the number of
available bytes.

As part of this patch, I also fixed one available() implementation which was
incorrectly throwing NS_BASE_STREAM_WOULD_BLOCK.
