[Fix](fold_const) MAKE_SET constant folding should clear

[linrrzqqq]

Problem Summary:

MAKE_SET uses bit &= ~(1 << pos) for clearing bits at high positions in the FE constant folding path, which leads to incorrect clearing of high bits when pos >= 32 due to integer shift modulo.

For Java int shifts, the shift distance is masked with 0x1F, which means only the low 5 bits are used:

• pos = 0..31 -> normal
• pos = 32 -> treated as 0
• pos = 33 -> treated as 1
• pos = 64 -> treated as 0 again

For inputs like: MAKE_SET(4294967296, ...)(4294967296 == 1L << 32)
expect: bit &= ~(1 << 32)
got: bit &= ~(1 << 0)
That does not clear bit 32 at all. So:

• bit stays unchanged and pos stays 32
• the loop never makes progress
• the same string is appended again and again
• Java throws OutOfMemoryError: Java heap space

before(FE constant folding failed or FE OOM):

[hello-stephen]

Thank you for your contribution to Apache Doris.
Don't know what should be done next? See How to process your PR.

Please clearly describe your PR:

1. What problem was fixed (it's best to include specific error reporting information). How it was fixed.
2. Which behaviors were modified. What was the previous behavior, what is it now, why was it modified, and what possible impacts might there be.
3. What features were added. Why was this function added?
4. Which code was refactored and why was this part of the code refactored?
5. Which functions were optimized and what is the difference before and after the optimization?

Review result: no blocking issue found.

Critical checkpoints:

• Goal: the PR fixes FE constant folding for MAKE_SET when clearing bit positions >= 32 by changing the mask to 1L << pos; this addresses the Java int-shift masking issue described in the PR.
• Scope: the authoritative GitHub PR file list shows a focused one-line FE fix plus one regression invocation. Local commit history in this checkout is a shallow/root snapshot, so I used the GitHub PR file metadata as the review scope authority.
• Parallel paths: BE MAKE_SET already clears with an unsigned 64-bit mask, so the FE fold path now matches the runtime path for high bits.
• Tests: the added testFoldConst case exercises MAKE_SET(4294967296, ...) with enough arguments to reach bit 32 and compares FE-folded output against no-fold output.
• Concurrency, lifecycle, config, persistence, and compatibility: not implicated by this FE executable-function mask change.
• User focus: no additional user focus was provided.

Subagent conclusions:

• optimizer-rewrite: no candidate findings; convergence round 1 returned NO_NEW_VALUABLE_FINDINGS.
• tests-session-config: no candidate findings; convergence round 1 returned NO_NEW_VALUABLE_FINDINGS.
• No candidates were accepted for inline comments; two suspicious points were dismissed in the shared ledger with code evidence.

Validation limits: I did not run regression tests or FE build locally because this checkout is not worktree-initialized and thirdparty/installed / thirdparty/installed/bin/protoc are absent.
