Revert "Lex: Use the correct types for MS integer suffixes"

This reverts commit r211426.

This broke the arm bots. The crash can be reproduced on X86 by running.

Lex: Use the correct types for MS integer suffixes

Something went wrong with r211426, it is an older version of this code
and should not have been committed.  It was reverted with r211434.

Original commit message:
We didn't properly implement support for the sized integer suffixes.
Suffixes like i16 were essentially ignored instead of mapping them to
the appropriately sized integer type.

This fixes PR20008.

The i128 suffix isn't always available.

This Lexer test unconditionally used the i128 integer literal suffix.
This suffix is only available to targets that have 128-bit arithmetic
support.

TextDiagnostic: print remark level diagnostics in bold too

The purpose of bolding these is to make them visually distinct from
continuations (supplemental note diagnostics). Therefore, the bolding applies
to all severities _including_ remarks -- it's not in any way an indicator of
priority. Also simplify and comment.

No tests.

Make WindowsToolChain portable

De-conditionalize as much as possible so we can start to fix this code.

No change in functionality.

WindowsToolChain: decouple build environment from the toolchain

Don't try to find the MSVC version that the binaries were built with. Doing so
defeats testing by causing invalid test passes on the build servers.

Whichever Visual Studio (or clang-cl.exe) edition was used to build the clang
package, it's strictly orthogonal and has no relation to software versions
available on the user's PC.

Enable WindowsToolChain on all native Windows builds

Make binaries built by MSVC, mingw and clang functionally equivalent. The
checks are trivially performed at runtime to eliminate functional differences
between supported configurations that used to be hard-coded.

TextDiagnosticPrinter: use the mapped level for remark flag computation

Custom diagnostics don't have a builtin class so this wouldn't have worked.
Reduces surface area of remark-related changes.
