meson seems to append '.lib' to all pkg-config libs on windows

Describe the bug

When I add hdf5 as a dependency to a C piece of code on windows, ie `

hdf5_dep = dependency('hdf5', language:'c', required: true)

I end up with a link failure of msvc

LINK : fatal error LNK1181: cannot open input file 'C:\ProgramData\mambaforge\Library\lib\libcurl.lib.lib'

The hdf5.pc used by meson was generated by a cmake build and contains:

prefix=C:/ProgramData/mambaforge/Library
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include

Name: hdf5
Description: HDF5 (Hierarchical Data Format 5) Software Library
Version: 1.14.3

Cflags: -I${includedir}
Libs: -L${libdir}  -lhdf5
Requires:
Libs.private:  -lshlwapi -lC:/ProgramData/mambaforge/Library/lib/libcurl.lib -loptimized -lC:/ProgramData/mambaforge/Library/lib/libssl.lib -ldebug -loptimized -lC:/ProgramData/mambaforge/Library/lib/libcrypto.lib -ldebug -lC:/ProgramData/mambaforge/Library/lib/z.lib -lC:/ProgramData/mambaforge/Library/lib/szip.lib -lC:/ProgramData/mambaforge/Library/lib/szip.lib
Requires.private:

The Libs.private seems to be a part added to the linking and modified by meson by appending a '.lib'

To Reproduce

Create a simple C program that do nothing but contains

#include "hdf5.h"

int main()
{
int a =1;
a = a+2;
return 0;
}

The meson.build should contains

hdf5_dep = dependency('hdf5', language:'c', required: true)

executable('myapp',
main.c,
dependencies: [hdf5_dep])

Expected behavior

Linking to hdf5 on windows should work and meson should not append ".lib" when it is already present at end of file.
