remove texture cache

[RacoonDog]

Changes:

• Remove ARMOR_TEXTURE_CACHE

The ARMOR_TEXTURE_CACHE only caches the creation of the Identifier object, which only takes a few nanoseconds and is less computationally expensive than the HashMap hashing function.

Benchmark      Mode  Cnt   Score   Error  Units
Main.cache     avgt    3  43.148 ± 1.571  ns/op
Main.no_cache  avgt    3  17.560 ± 2.166  ns/op

Moreover, the ARMOR_TEXTURE_CACHE persistently holds multiple Identifier and String objects, resulting in a maximum memory usage of 1264 bytes in vanilla, possibly more with mods involved.

The changes present in this pull request are also applicable to the forge versions.
