[llvm][NFC] Fix typos: replace “avaliable” with “available” across various files (llvm#114524)

This pull request corrects multiple occurrences of the typo "avaliable"
to "available" across the LLVM and Clang codebase. These changes improve
the clarity and accuracy of comments and documentation. Specific
modifications are in the following files:

1. clang-tools-extra/clang-tidy/readability/FunctionCognitiveComplexityCheck.cpp:
Updated comments in readability checks for cognitive complexity.
2. llvm/include/llvm/ExecutionEngine/Orc/ExecutionUtils.h: Corrected
documentation for JITDylib responsibilities.
3. llvm/include/llvm/Target/TargetMacroFusion.td: Fixed descriptions for
FusionPredicate variables.
4. llvm/lib/CodeGen/SafeStack.cpp: Improved comments on DominatorTree
availability.
5. llvm/lib/Target/RISCV/RISCVSchedSiFive7.td: Enhanced resource usage
descriptions for vector units.
6. llvm/lib/Transforms/Scalar/LoopIdiomRecognize.cpp: Updated invariant
description in shift-detect idiom logic.
7. llvm/test/MC/ARM/mve-fp-registers.s: Amended ARM MVE register
availability notes.
8. mlir/lib/Bytecode/Reader/BytecodeReader.cpp: Adjusted forward
reference descriptions for bytecode reader operations.

These changes have no impact on code functionality, focusing solely on
documentation clarity.
