pixman: fixing inline failure with -Og

When debug build is enabled(-Og is used), pixman-native do_compile
failed with error:
In function ‘combine_inner’,
    inlined from ‘combine_soft_light_ca_float’ at ../pixman-0.42.2/pixman/pixman-combine-float.c:655:1:
../pixman-0.42.2/pixman/pixman-combine-float.c:370:5: error: inlining failed in call to ‘always_inline’ ‘combine_soft_light_c’: function not considered for inlining
  370 |     combine_ ## name ## _c (float sa, float s, float da, float d)

Refer [1], always_inline is not suggested to use with indirect function
call, replace always_inline with __inline__ to fix the issue

+Refer [1], always-inline is not suggested to be used if you have indirect
+calls. so replace force_inline with inline to fix error:
