[AMDGPU][True16][MC] add fake16 error and promote test (#135984)

This is a NFC patch.

Added error and promote test for fake16 flow. This includes two part:
1. "*vop1_t16_err-fake16.s" is renamed to "*vop1_fake16_err.s"
2. added missing "fake16-promote.s" and other "*fake16_err.s" files

These tests are about promoting the instruction encoding to 64 bits if
the used registers are not encodable in the 32-bit form.
