refactor: correct GetFlogSize to read UINT32

[sinchubhat]

• Changed FlogSize from uint16 (2 bytes) to uint32 (4 bytes) to match Intel HOTHAM specification.
• Cleaned up Windows trace logs.
• Updated Linux GUID to match Windows standard format.

Pull request overview

This PR corrects the GetFlogSize function to properly read UINT32 values (4 bytes) instead of UINT16 values (2 bytes) to align with the Intel HOTHAM specification. It also refactors error message handling on Linux and reduces verbose trace logging on Windows.

Changes:

• Updated GetFlogSizeResponse.Size field from uint16 to uint32 to match spec
• Modified response parsing logic to read 4 bytes instead of 2 bytes for the size field
• Refactored duplicate error message strings into constants on Linux
• Removed excessive trace logging statements on Windows

LGTM, please check this one difference in the way guid is being printed on windows and linux

Hi, updated Linux GUID to match Windows standard format.
Earlier:
Windows Format:
{082EE5A7-7C25-470A-9643-0C06F0466EA1}
Standard Windows GUID format with braces and hyphens.
Linux Format:
a7e52e08257c0a4796430c06f0466ea1
Raw hex byte array

Breaking down Linux bytes: a7 e5 2e 08 25 7c 0a 47 96 43 0c 06 f0 46 6e a1
Reading with proper GUID byte ordering:

First 4 bytes reversed: a7e52e08 → 082EE5A7 ✓
Next 2 bytes reversed: 257c → 7C25 ✓
Next 2 bytes reversed: 0a47 → 470A ✓
Last 8 bytes as-is: 96430c06f0466ea1 → 9643-0C06F0466EA1 ✓
Result: {082EE5A7-7C25-470A-9643-0C06F0466EA1} - Same GUID!
