Add a WASM parser/disassembler for KolibriOS in x86 FASM.
Parses all 12 sections of the WASM binary format and prints out output.
Tested on real WASM binaries (QEMU).
Sections: type, import, function, table, memory, global, export,
start, element, data, custom.

Note:
leb128_decode_i64 is not implemented yet correctly
i64.const parser function is currently stubbed
Code section is currently being skipped

disassembly output. Tested against real WASM binaries.

Sections implemented: type, import, function, table, memory, global,
export, start, element, data, custom. Code section parsing is planned
for the next commit.
