[lldb][lldb-dap] Fix compilation error on 32 bit platforms

https://github.com/llvm/llvm-project/pull/109485 tried to std::min
between size_t and uint64_t. size_t on 32 bit is 32 bits.

https://lab.llvm.org/buildbot/#/builders/18/builds/4430/steps/4/logs/stdio

Explicitly select the size_t template to fix this.

This will truncate one of the arguments but that's the count_requested.
If you're debugging from a 32 bit host and you asked it to read
> 32 bit range of memory from a 64 bit target, you weren't going
to have any success anyway.

The final result needs to be size_t to resize the vector with.
