Subject: [PATCH] Fixed hex numbers for integer literal

Description: Hex numbers are now treated like decimal numbers.
That is, the hex value is now signed.
Example (for "int"): -10 (decimal) is now -0x0000000A (hex)
rather than 0xFFFFFFF6 (hex).
However, when overflowing for hex, the integer literal type does
not expand to "double" as it does with decimal representation.

Issue: https://gitee.com/openharmony/arkcompiler_ets_frontend/issues/IACNIB

Testing: run tests: parser, ets-cts, ets-func-tests.
