[wasm][R2R] Re-enable b51875 and b77707 after #134979

[lewing]

These JIT regression tests were quarantined for wasm ReadyToRun in #134960 against #134975 (an exception thrown from a finally was reported as unhandled instead of reaching the caller's catch). #134979 ("JIT: make Wasm frames that call a finally unwindable") fixed that and closed #134975, so this removes the three ActiveIssue attributes:

• JIT/Regression/CLR-x86-JIT/V1-M12-Beta2/b51875/b51875.cs (runner Regression_8)
• JIT/Regression/CLR-x86-JIT/V1-M12-Beta2/b51875/Desktop/b51875.cs (runner Regression_PdbOnly_r_2)
• JIT/Regression/CLR-x86-JIT/V1-M12-Beta2/b77707/b77707.cs (runner Regression_PdbOnly_r_2)

Local validation (macOS arm64, branch includes 9997fdf)
