[lldb][LoongArch] Function calls support in lldb expressions

This patch adds desired feature flags in JIT compiler to enable
hard-float instructions if target supports them and allows to use floats
and doubles in lldb expressions.

Fited tests:
lldb-shell :: Expr/TestAnonNamespaceParamFunc.cpp
lldb-shell :: Expr/TestIRMemoryMap.test
lldb-shell :: Expr/TestStringLiteralExpr.test
lldb-shell :: SymbolFile/DWARF/debug-types-expressions.test
