Add static storage classifier to inline functions

Before we were just relying on the compiler inlining them and not
leaving a trace in our public API. Try to fix. Hopefully not
breaking anyone's build.

[otlayout] Fix (Chain)Context recursion!
...
Previously we only supported recursive sublookups with
ascending indices. We were also not correctly handling
non-1-to-1 recursed lookups.
Fix all that!
Fixes the three tests in test/shaping/tests/context-matching.tests,
which were derived from NotoSansBengali and NotoSansDevanagari
among others.

[OTLayout] Ignore default-ignorables when matching GSUB/GPOS
...
When matching lookups, be smart about default-ignorable characters.
In particular:
Do nothing specific about ZWNJ, but for the other default-ignorables:
If the lookup in question uses the ignorable character in a sequence,
then match it as we used to do. However, if the sequence match will
fail because the default-ignorable blocked it, try skipping the
ignorable character and continue.
The most immediate thing it means is that if Lam-Alef forms a ligature,
then Lam-ZWJ-Alef will do to. Finally!
One exception: when matching for GPOS, or for backtrack/lookahead of
GSUB, we ignore ZWNJ too. That's the right thing to do.
It certainly is possible to build fonts that this feature will result
in undesirable glyphs, but it's hard to think of a real-world case
that that would happen.
This *does* break Indic shaping right now, since Indic Unicode has
specific rules for what ZWJ/ZWNJ mean, and skipping ZWJ is breaking
those rules. That will be fixed in upcoming commits.
