[aat] Consume glyph insertion from buffer's max_ops (#2223) 
Glyph insertion is an expensive operation and we like to have it limited
based on buffer's input size which is handled by buffer's max_ops.

clusterfuzz-testcase-minimized-harfbuzz_fuzzer-5754958982021120:

Before the change: 0.67s user 0.00s system 99% cpu 0.674 total
 After the change: 0.02s user 0.00s system 98% cpu 0.024 total

Which takes much longer on valgrind and tsan bots.

[aat] Correct array indexing when looking up actions in KerxSubTableFormat4 (#2539) 
* [aat] Correct array indexing when looking up actions in KerxSubTableFormat4.

- For action_type 0 and 1, there are 2 values per action record; for action_type 2, there are 4. So we need to account for these factors when indexing into the ankrData array.

Fixes https://github.com/harfbuzz/harfbuzz/issues/2531.

122a2897e4 [aat] Remove lcar support 
Very low use, only two distinct font files, Apple Chancery.ttf and Hoefler Text.ttc
have it so it really doesn't worth the size addition and so, but one may argue that
whole ligature caret is low use but guess we better to encourage GDEF one anyway.

a470b0b205 Minor, disable strict-aliasing warning in set fuzzer

And it is already disabled at project level so let's disable it here also.
