Subject: [PATCH] Disable -Wunused-macros under GCC

Since the pragram in hb-ot-shape-complex-indic-table.cc didn't seem to
silence GCC, eg:

../../src/hb-ot-shape-complex-indic-table.cc:55: warning: macro "ISC_TL" is not used [-Wunused-macros]
   55 | #define ISC_TL   INDIC_SYLLABIC_CATEGORY_TONE_LETTER                 /*    7 chars; Tone_Letter */

disable it at compiler level.
