[LoongArch][Codegen] Add support for TLSDESC The implementation only enables when the `-enable-tlsdesc` option is passed and the TLS model is `dynamic`. LoongArch's GCC has the same option(-mtls-dialet=) as RISC-V. Reviewers: heiher, MaskRay, SixWeining Reviewed By: SixWeining, MaskRay Pull Request: https://github.com/llvm/llvm-project/pull/90159

[Driver,CodeGen] Support -mtls-dialect= (#79256) GCC supports -mtls-dialect= for several architectures to select TLSDESC. This patch supports the following values * x86: "gnu". "gnu2" (TLSDESC) is not supported yet. * RISC-V: "trad" (general dynamic), "desc" (TLSDESC, see #66915) AArch64 toolchains seem to support TLSDESC from the beginning, and the general dynamic model has poor support. Nobody seems to use the option -mtls-dialect= at all, so we don't bother with it. There also seems very little interest in AArch32's TLSDESC support. TLSDESC does not change IR, but affects object file generation. Without a backend option the option is a no-op for in-process ThinLTO. There seems no motivation to have fine-grained control mixing trad/desc for TLS, so we just pass -mllvm, and don't bother with a modules flag metadata or function attribute.
